-\csa{xintCSVtoList}|{a,b,c...,z}|\etype{f} returns |{a}{b}{c}...{z}|. A
-\emph{list} is by
-convention in this manual simply a succession of tokens, where each braced thing
-will count as one item (``items'' are defined according to the rules of \TeX{}
-for fetching undelimited parameters of a macro, which are exactly the same rules
-as for \LaTeX{} and macro arguments [they are the same things]). The word
-`list' in `comma separated list of items' has its usual linguistic meaning,
-and then an ``item'' is what is delimited by commas.
-
-So \csa{xintCSVtoList} takes on input a `comma separated list of items' and
-converts it into a `\TeX{} list of braced items'. The argument to
-|\xintCSVtoList| may be a macro: it will first be
-\hyperref[ssec:expansions]{\fexpan ded}. Hence the item before the first comma,
-if it is itself a macro, will be expanded which may or may not be a good thing.
-A space inserted at the start of the first item serves to stop that expansion
-(and disappears). The macro \csbxint{CSVtoListNoExpand}\etype{n} does the same
-job without
-the initial expansion of the list argument.
-
-Apart from that no expansion of the items is done and the list items may thus be
-completely arbitrary (and even contain perilous stuff such as unmatched |\if|
-and |\fi| tokens).
-
-Contiguous spaces and tab characters, are collapsed by \TeX{}
-into single spaces. All such spaces around commas%
-%
-\footnote{and multiple space tokens are not a problem; but those at the
- top level (not hidden inside braces) \emph{must} be of character code
- |32|.}
-%
-\fbox{are removed}, as well as
-the spaces at the start and the spaces at the end of the list.%
-%
-\footnote{let us recall that this is all done completely expandably...
- There is absolutely no alteration of any sort of the item apart from
- the stripping of initial and final space tokens (of character code
- |32|) and brace removal if and only if the item apart from intial and
- final spaces (or more generally multiple |char 32| space tokens) is
- braced.}
-%
-The items may contain explicit |\par|'s or
-empty lines (converted by the \TeX{} input parsing into |\par| tokens).

-One sees on this example how braces protect commas from
-sub-lists to be perceived as delimiters of the top list. Braces around an entire
-item are removed, even when surrounded by spaces before and/or after. Braces for
-sub-parts of an item are not removed.
-
-We observe also that there is a slight difference regarding the brace stripping
-of an item: if the braces were not surrounded by spaces, also the initial and
-final (but no other) spaces of the \emph{enclosed} material are removed. This is
-the only situation where spaces protected by braces are nevertheless removed.
-
-From the rules above: for an empty argument (only spaces, no braces, no comma)
-the output is
-\dtt{\expandafter\detokenize\expandafter{\romannumeral0\xintcsvtolist { }}}
-(a list with one empty item),
-for ``|<opt. spaces>{}<opt.
-spaces>|'' the output is
-\dtt{\expandafter\detokenize\expandafter
- {\romannumeral0\xintcsvtolist { {} }}}
-(again a list with one empty item, the braces were removed),
-for ``|{ }|'' the output is
-\dtt{\expandafter\detokenize\expandafter
- {\romannumeral0\xintcsvtolist {{ }}}}
-(again a list with one empty item, the braces were removed and then
-the inner space was removed),
-for ``| { }|'' the output is
-\dtt{\expandafter\detokenize\expandafter
-{\romannumeral0\xintcsvtolist { { }}}} (again a list with one empty item, the initial space served only to stop the expansion, so this was like ``|{ }|'' as input, the braces were removed and the inner space was stripped),
-for ``\texttt{\ \{\ \ \}\ }'' the output is
-\dtt{\expandafter\detokenize\expandafter
-{\romannumeral0\xintcsvtolist { { } }}} (this time the ending space of the first
-item meant that after brace removal the inner spaces were kept; recall though
-that \TeX{} collapses on input consecutive blanks into one space token),
-for ``|,|'' the output consists of two consecutive
-empty items
-\dtt{\expandafter\detokenize\expandafter{\romannumeral0\xintcsvtolist
- {,}}}. Recall that on output everything is braced, a |{}| is an ``empty''
-item.
-%
-Most of the above is mainly irrelevant for every day use, apart perhaps from the
-fact to be noted that an empty input does not give an empty output but a
-one-empty-item list (it is as if an ending comma was always added at the end of
-the input).

-The results above were automatically displayed using \TeX's primitive

-\def\macro #1{\the\numexpr 9-#1\relax}
-
-\csa{xintApply}|{\macro}|\marg{list}\etype{ff} expandably applies the one
-parameter macro |\macro| to each item in the \meta{list} given as second
-argument and returns a new list with these outputs: each item is given one after
-the other as parameter to |\macro| which is expanded at that time (as usual,
-\emph{i.e.} fully for what comes first), the results are braced and output
-together as a succession of braced items (if |\macro| is defined to start with a
-space, the space will be gobbled and the |\macro| will not be expanded; it is
-allowed to have its own arguments, the list items serve as last arguments to
-|\macro|). Hence |\xintApply{\macro}{{1}{2}{3}}| returns
-|{\macro{1}}{\macro{2}}{\macro{3}}| where all instances of |\macro| have been
-already \fexpan ded.
-
-Being expandable, |\xintApply| is useful for example inside alignments where
-implicit groups make standard loops constructs usually fail. In such situation
-it is often not wished that the new list elements be braced, see
-\csbxint{ApplyUnbraced}. The |\macro| does not have to be expandable:
-|\xintApply| will try to expand it, the expansion may remain partial.
-
-The \meta{list} may
-itself be some macro expanding (in the previously described way) to the list of
-tokens to which the macro |\macro| will be applied. For example, if the
-\meta{list} expands to some positive number, then each digit will be replaced by
-the result of applying |\macro| on it. %

-opposite signs, the macro returns nothing. If the optional argument |d| is
-omitted it is taken to be the sign of |y-x|. Hence |\xintSeq {1}{0}| is not
-empty but |{1}{0}|. But |\xintSeq [1]{1}{0}| is empty.

-One can abort the loop with \csbxint{breakloop}; this should not be used inside
-the final test, and one should expand the |\fi| from the corresponding test
-before. One has also \csbxint{breakloopanddo} whose first argument will be
-inserted in the token stream after the loop; one may need a macro such as
-|\xint_afterfi| to move the whole thing after the |\fi|, as a simple
-|\expandafter| will not be enough.
-
-One will usually employ some count registers to manage the exit test from the
-loop; this breaks expandability, see \csbxint{iloop} for an expandable integer
-indexed loop. Use in alignments will be complicated by the fact that cells
-create groups, and also from the fact that any encountered unexpandable material
-will cause the \TeX{} input scanner to insert |\endtemplate| on each encountered
-|&| or |\cr|; thus |\xintbreakloop| may not work as expected, but the situation
-can be resolved via |\xint_firstofone{&}| or use of |\TAB| with |\def\TAB{&}|.
-It is thus simpler for alignments to use rather than \csbxint{loop} either the
-expandable \csbxint{ApplyUnbraced} or the non-expandable but alignment
-compatible \csbxint{ApplyInline}, \csbxint{For} or \csbxint{For*}.
-
-As an example, let us suppose we have two macros |\A|\marg{i}\marg{j} and
-|\B|\marg{i}\marg{j} behaving like (small) integer valued matrix entries, and we
-want to define a macro |\C|\marg{i}\marg{j} giving the matrix product (|i| and
-|j| may be count registers). We will assume that |\A[I]| expands to the number
-of rows, |\A[J]| to the number of columns and want the produced |\C| to act in
-the same manner. The code is very dispendious in use of |\count| registers, not
-optimized in any way, not made very robust (the defined macro can not have the
-same name as the first two matrices for example), we just wanted to quickly
-illustrate use of the nesting capabilities of |\xintloop|.%

-
-\csa{xintiloop}|[start+delta]|\meta{stuff}|\if<test> ... \repeat|\retype{} is a
-completely expandable nestable loop. complete expandability depends naturally on
-the actual iterated contents, and complete expansion will not be achievable
-under a sole \fexpan sion, as is indicated by the hollow star in the margin;
-thus the loop can be used inside an |\edef| but not inside arguments to the
-package macros. It can be used inside an |\xintexpr..\relax|. The
-|[start+delta]| is mandatory, not optional.
-
-This loop benefits via \csbxint{iloopindex} to (a limited access to) the integer
-index of the iteration. The starting value |start| (which may be a |\count|) and
-increment |delta| (\emph{id.}) are mandatory arguments. A space after the
-closing square bracket is not significant, it will be ignored. Spaces inside the
-square brackets will also be ignored as the two arguments are first given to a
-|\numexpr...\relax|. Empty lines and explicit |\par| tokens are accepted.
-
-As with \csbxint{loop}, this tool will mostly be of interest to advanced users.
-For nesting, one puts inside braces all the
-material from the start (immediately after |[start+delta]|) and up to and
-inclusive of the inner loop, these braces will be removed and do not create a
-loop. In case of nesting, \csbxint{outeriloopindex} gives access to the index of
-the outer loop. If needed one could write on its model a macro giving access to
-the index of the outer outer loop (or even to the |nth| outer loop).
-
-The \csa{xintiloopindex} and \csa{xintouteriloopindex} can not be used inside
-braces, and generally speaking this means they should be expanded first when
-given as argument to a macro, and that this macro receives them as delimited
-arguments, not braced ones. Or, but naturally this will break expandability, one
-can assign the value of \csa{xintiloopindex} to some |\count|. Both
-\csa{xintiloopindex} and \csa{xintouteriloopindex} extend to the litteral
-representation of the index, thus in |\ifnum| tests, if it comes last one has to
-correctly end the macro with a |\space|, or encapsulate it in a
-|\numexpr..\relax|.
-
-When the repeat-test of the loop is, for example, |\ifnum\xintiloopindex<10
-\repeat|, this means that the last iteration will be with |\xintiloopindex=10|
-(assuming |delta=1|). There is also |\ifnum\xintiloopindex=10 \else\repeat| to
-get the last iteration to be the one with |\xintiloopindex=10|.
-
-One has \csbxint{breakiloop} and \csbxint{breakiloopanddo} to abort the loop.
-The syntax of |\xintbreakiloopanddo| is a bit surprising, the sequence of tokens
-to be executed after breaking the loop is not within braces but is delimited by
-a dot as in:
-%
-\leftedline{|\xintbreakiloopanddo <afterloop>.etc.. etc... \repeat|}
-%
-The reason is that one may wish to use the then current value of
-|\xintiloopindex| in |<afterloop>| but it can't be within braces at the time it
-is evaluated. However, it is not that easy as |\xintiloopindex| must be expanded
-before, so one ends up with code like this:
-%
-\leftedline
-{|\expandafter\xintbreakiloopanddo\expandafter\macro\xintiloopindex.%|}
-%
-\leftedline{|etc.. etc.. \repeat|}
-%
-As moreover the |\fi| from the test leading to the decision of breaking out of
-the loop must be cleared out of the way, the above should be
-a branch of an expandable conditional test, else one needs something such
-as:
-%
-\leftedline
-{|\xint_afterfi{\expandafter\xintbreakiloopanddo\expandafter\macro\xintiloopindex.}%|}
-%
-\leftedline{|\fi etc..etc.. \repeat|}
-
-There is \csbxint{iloopskiptonext} to abort the current iteration and skip to
-the next, \hyperref[xintiloopskipandredo]{\ttfamily\hyphenchar\font45 \char92
- xintiloopskip\-and\-redo} to skip to the end of the current iteration and redo
-it with the same value of the index (something else will have to change for this
-not to become an eternal loop\dots ).
-
-Inside alignments, if the looped-over text contains a |&| or a |\cr|, any
-un-expandable material before a \csbxint{iloopindex} will make it fail because
-of |\endtemplate|; in such cases one can always either replace |&| by a macro
-expanding to it or replace it by a suitable |\firstofone{&}|, and similarly for
-|\cr|.
-
-\phantomsection\label{edefprimes}

-

-\subsection{\csbh{xintApplyInline}}\label{xintApplyInline}
-
-
-\csa{xintApplyInline}|{\macro}|\marg{list}\ntype{o{\lowast f}} works non
-expandably. It applies the one-parameter |\macro| to the first element of the
-expanded list (|\macro| may have itself some arguments, the list item will be
-appended as last argument), and is then re-inserted in the input stream after
-the tokens resulting from this first expansion of |\macro|. The next item is
-then handled.
-
-This is to be used in situations where one needs to do some repetitive
-things. It is not expandable and can not be completely expanded inside a
-macro definition, to prepare material for later execution, contrarily to what
-\csbxint{Apply} or \csbxint{ApplyUnbraced} achieve.
-
-\begin{everbatim*}
-\def\Macro #1{\advance\cnta #1 , \the\cnta}
-\cnta 0
-0\xintApplyInline\Macro {3141592653}.
-\end{everbatim*}
-The first argument |\macro| does not have to be an expandable macro.
-
-\csa{xintApplyInline} submits its second, token list parameter to an
-\hyperref[ssec:expansions]{\fexpan
-sion}. Then, each \emph{unbraced} item will also be \fexpan ded. This provides
-an easy way to insert one list inside another. \emph{Braced} items are not
-expanded. Spaces in-between items are gobbled (as well as those at the start
-or the end of the list), but not the spaces \emph{inside} the braced items.
-
-\csa{xintApplyInline}, despite being non-expandable, does survive to
-contexts where the executed |\macro| closes groups, as happens inside
-alignments with the tabulation character |&|.
-This tabular provides an example:\par
-\begin{everbatim*}
-\centerline{\normalcolor\begin{tabular}{ccc}
- $N$ & $N^2$ & $N^3$ \\ \hline
- \def\Row #1{ #1 & \xintiiSqr {#1} & \xintiiPow {#1}{3} \\ \hline }%
- \xintApplyInline \Row {\xintCSVtoList{17,28,39,50,61}}
-\end{tabular}}\medskip
-\end{everbatim*}
-
-We see that despite the fact that the first encountered tabulation character in
-the first row close a group and thus erases |\Row| from \TeX's memory,
-|\xintApplyInline| knows how to deal with this.
-
-Using \csbxint{ApplyUnbraced} is an alternative: the difference is that
-this would have prepared all rows first and only put them back into the
-token stream once they are all assembled, whereas with |\xintApplyInline|
-each row is constructed and immediately fed back into the token stream: when
-one does things with numbers having hundreds of digits, one learns that
-keeping on hold and shuffling around hundreds of tokens has an impact on
-\TeX{}'s speed (make this ``thousands of tokens'' for the impact to be
-noticeable).
-
-One may nest various |\xintApplyInline|'s. For example (see the
-\hyperref[float]{table} \vpageref{float}):\par
-\begin{everbatim*}
-\begin{figure*}[ht!]
- \centering\phantomsection\label{float}
- \def\Row #1{#1:\xintApplyInline {\Item {#1}}{0123456789}\\ }%
- \def\Item #1#2{&\xintiPow {#1}{#2}}%
- \centeredline {\begin{tabular}{ccccccccccc} &0&1&2&3&4&5&6&7&8&9\\ \hline
- \xintApplyInline \Row {0123456789}
- \end{tabular}}
-\end{figure*}
-\end{everbatim*}
-
-One could not move the definition of |\Item| inside the tabular,
-as it would get lost after the first |&|. But this
-works:
-\everb|@
-\begin{tabular}{ccccccccccc}
- &0&1&2&3&4&5&6&7&8&9\\ \hline
- \def\Row #1{#1:\xintApplyInline {&\xintiPow {#1}}{0123456789}\\ }%
- \xintApplyInline \Row {0123456789}
-\end{tabular}
-|
-
-A limitation is that, contrarily to what one may have expected, the
-|\macro| for an |\xintApplyInline| can not be used to define
-the |\macro| for a nested sub-|\xintApplyInline|. For example,
-this does not work:\par
-\everb|@
- \def\Row #1{#1:\def\Item ##1{&\xintiPow {#1}{##1}}%
- \xintApplyInline \Item {0123456789}\\ }%
- \xintApplyInline \Row {0123456789} % does not work
-|
-\noindent But see \csbxint{For}.
-
-\subsection{\csbh{xintFor}, \csbh{xintFor*}}\label{xintFor}\label{xintFor*}
-
-\csbxint{For}\ntype{on} is a new kind of for loop.\footnote{first introduced
- with \xintname |1.09c| of |2013/10/09|.} Rather than using macros
-for encapsulating list items, its behavior is like a macro with parameters:
-|#1|, |#2|, \dots, |#9| are used to represent the items for up to nine levels of
-nested loops. Here is an example:
+Other macros, such as \csbxint{Double}, lack the |ii|, but this is only a
+legacy of the history of the package and they have the same requirements for
+input and format of output as the |ii|-macros.%
%
-\everb|@
-\xintFor #9 in {1,2,3} \do {%
- \xintFor #1 in {4,5,6} \do {%
- \xintFor #3 in {7,8,9} \do {%
- \xintFor #2 in {10,11,12} \do {%
- $$#9\times#1\times#3\times#2=\xintiiPrd{{#1}{#2}{#3}{#9}}$$}}}}
-|
-\noindent This example illustrates that one does not have to use |#1| as the
-first one:
-the order is arbitrary. But each level of nesting should have its specific macro
-parameter. Nine levels of nesting is presumably overkill, but I did not know
-where it was reasonable to stop. |\par| tokens are accepted in both the comma
-separated list and the replacement text.
+\footnote{Regarding \csbxint{FDg} and \csbxint{LDg}, this is a breaking change
+ because formerly they used \csbxint{Num}.}
-\begin{framed}
- \TeX nical notes:
+The letter \texttt{x} (with margin annotation
+\smash{\textcolor[named]{PineGreen}{\numx}}) stands for an argument which will
+be handled embedded in |\numexpr..\relax|. It will thus be completely expanded
+and must give an integer obeying the \TeX{} bounds. See also
+\autoref{sec:useofcount}. This is the case for the argument of \csbxint{iiFac}
+or the exponent argument of \csbxint{iiPow}.
-\begin{itemize}
- \item The |#1| is replaced in the iterated-over text exactly as in general
- \TeX\ macros or \LaTeX\ commands. This spares the user quite a few
- |\expandafter|'s or other tricks needed with loops which have the
- values encapsulated in macros, like \LaTeX's |\@for| and |\@tfor|.
+The {\color[named]{PineGreen}$\star$}'s in the margin are there to remind of
+the complete expandability, even \fexpan dability of the macros, as discussed
+in \autoref{ssec:expansions}.
- \item \csa{xintFor} (and \csa{xintFor*}) isn't purely expandable: one can
- not use it inside an |\edef|. But it may be used, as will be shown in
- examples, in some contexts such as \LaTeX's |tabular| which are usually
- hostile to non-expandable loops.
-
- \item \csa{xintFor} (and \csa{xintFor*}) does some assignments prior to
- executing each iteration of the replacement text, but it acts purely
- expandably after the last iteration, hence if for example the replacement
- text ends with a |\\|, the loop can be used insided a tabular and be
- followed by a |\hline| without creating the dreaded ``|Misplaced
- \noalign|'' error.
+\subsection{\csbh{xintiNum}}\label{xintiNum}
- \item It does not create groups.
-
- \item It makes no global assignments.
-
- \item The iterated replacement text may close a group which was opened even
- before the start of the loop (typical example being with |&| in
- alignments).
+|\xintiNum|\n\etype{f} removes chains of plus or minus signs, followed by
+zeroes.
\begin{everbatim*}
-\begin{tabular}{rccccc}

-\end{tabular}
+\xintiNum{+---++----+--000000000367941789479}
\end{everbatim*}
-
- \item There is no facility provided which would give access to a count of
- the number of iterations as it is technically not easy to do so it in a
- way working with nested loops while maintaining the ``expandable after
- done'' property; something in the spirit of \csbxint{iloopindex} is
- possible but this approach would bring its own limitations and
- complications. Hence the user is invited to update her own count or
- \LaTeX{} counter or macro at each iteration, if needed.
- \item A |\macro| whose definition uses internally an \csbxint{For} loop
- may be used inside another \csbxint{For} loop even if the two loops both
- use the same macro parameter. The loop definition inside |\macro|
- must use |##| as is the general rule for definitions done inside macros.
+\subsection{\csbh{xintDouble}}\label{xintDouble}
- \item \csbxint{For} is for comma separated values and \csbxint{For*} for
- lists of braced items; their respective expansion policies differ. They
- are described later.

-\unskip
-\end{framed}
+|\xintDouble|\n\etype{f} computes |2N|.
-\noindent Regarding \csbxint{For}:
-\begin{itemize}[nosep, listparindent=\leftmarginiii]
-\item the spaces between the various declarative elements are all optional,
-\item in the list of comma separated values, spaces around the commas or at
- the start and end are ignored,
-\item if an item must contain itself its own commas, then it should
- be braced, and the braces will be removed before feeding the iterated-over
- text,
-\item the list may be a macro, it is expanded only once,
-\item items are not pre-expanded. The first item should be braced or start
- with a space if the list is explicit and the item should not be
- pre-expanded,
-\item empty items give empty |#1|'s in the replacement text, they are not
- skipped,
-\item an empty list executes once the replacement text with an empty parameter
- value,
-\item the list, if not a macro, \fbox{must be braced.}
-\end{itemize}
+\subsection{\csbh{xintHalf}}\label{xintHalf}
-\noindent Regarding \csbxint{For*}:\ntype{{\lowast f}n}
-\begin{itemize}[nosep, listparindent=\leftmarginiii]
-\item it handles lists of braced items (or naked tokens),
-\item it \hyperref[ssec:expansions]{\fexpan ds} the list,
-\item and more generally it \hyperref[ssec:expansions]{\fexpan ds} each naked
- token encountered
- before assigning the |#1| values (gobbling spaces in the process);
- this
- makes it easy to simulate concatenation of multiple lists|\x|, |\y|:
- if |\x| expands to |{1}{2}{3}| and |\y| expands to |{4}{5}{6}| then |{\x\y}|
- as argument to |\xintFor*| has the same effect as |{{1}{2}{3}{4}{5}{6}}|.
+|\xintHalf|\n\etype{f} computes |N/2|
+truncated towards zero.
- For a further illustration see the use of |\xintFor*| at the end of
- \autoref{ssec:fibonacci}.
-\item spaces at the start, end, or in-between items are gobbled (but naturally
- not the spaces inside \emph{braced} items),
-\item except if the list argument is a macro (with no parameters), \fbox{it
- must be braced.},
-\item an empty list leads to an empty result.
-\end{itemize}
+\subsection{\csbh{xintInc}}\label{xintInc}

-When nesting \csa{xintFor*} loops, using \csa{xintSeq} in the inner loops is
-inefficient, as the arithmetic sequence will be re-created each time. A more
-efficient style is:
-%
-\begin{everbatim}
- \edef\innersequence {\xintSeq[+2]{-50}{50}}%
- \xintFor* #1 in {\xintSeq {13}{27}} \do
- {\xintFor* #2 in \innersequence \do {stuff with #1 and #2}%
- .. some other macros .. }
-\end{everbatim}
+|\xintDec|\n\etype{f} evaluates |N-1|.
-This is a general remark applying for any nesting of loops, one should avoid
-recreating the inner lists of arguments at each iteration of the outer loop.
+\subsection{\csbh{xintDSL}}\label{xintDSL}
+|\xintDSL|\n\etype{f} is decimal shift left, \emph{i.e.} multiplication by
+ten.
-When the loop is defined inside a macro for later execution the |#| characters
-must be doubled.%
-%
-\footnote{sometimes what seems to be a macro argument isn't really; in
- \csa{raisebox\{1cm\}\{}\csa{xintFor \#1 in \{a,b,c\} }\csa{do
- \{\#1\}\}} no doubling should be done.}
-%
-For example:
-%
-\begin{everbatim*}
-\def\T{\def\z {}%
- \xintFor* ##1 in {{u}{v}{w}} \do {%
- \xintFor ##2 in {x,y,z} \do {%
- \expandafter\def\expandafter\z\expandafter {\z\sep (##1,##2)} }%
- }%
-}%
-\T\def\sep {\def\sep{, }}\z
-\end{everbatim*}
+\subsection{\csbh{xintDSR}}\label{xintDSR}
-Similarly when the replacement text
-of |\xintFor| defines a macro with parameters, the macro character |#| must be
-doubled.
+|\xintDSR|\n\etype{f} is truncated decimal shift right, \emph{i.e.} it is the
+truncation of |N/10| towards zero.
+\subsection{\csbh{xintDSRr}}\label{xintDSRr}
-The iterated macros as well as the list items are allowed to contain explicit
-|\par| tokens.
+|\xintDSRr|\n\etype{f} is rounded decimal shift right, \emph{i.e.} it is the
+rounding of |N/10| away from zero. It is needed in \xintcorename for use by
+\csbxint{iiDivRound}.\NewWith {1.2i}
+\subsection{\csbh{xintFDg}}\label{xintFDg}
-\subsection{\csbh{xintifForFirst}, \csbh{xintifForLast}}
-\label{xintifForFirst}\label{xintifForLast}
+|\xintFDg|\n\etype{f} outputs the first digit (most significant) of the
+number.
-\csbxint{ifForFirst}\,\texttt{\{YES branch\}\{NO branch\}}\etype{nn}
- and \csbxint{ifForLast}\,\texttt{\{YES
- branch\}\hskip 0pt plus 0.2em \{NO branch\}}\etype{nn} execute the |YES| or
-|NO| branch
-if the
-\csbxint{For}
-or \csbxint{For*} loop is currently in its first, respectively last, iteration.
+\subsection{\csbh{xintLDg}}\label{xintLDg}
-Designed to work as expected under nesting (but see frame next.) Don't forget
-an empty brace pair |{}| if a branch is to do nothing. May be used multiple
-times in the replacement text of the loop.
+|\xintLDg|\n\etype{f} outputs the least significant digit. When the number
+is positive, this is the same as the remainder in the euclidean division by
+ten.
-\begin{framed}
- \noindent Pay attention to these implementation features:
- \begin{itemize}[nosep, listparindent=\leftmarginiii]
- \item \emph{if an inner \csbxint{For} loop is positioned before the
- \csb{xintifForFirst} or \csb{xintifForLast} of the outer loop it will
- contaminate their settings. This applies also naturally if the inner loop
- arises from the expansion of some macro located before the outer
- conditionals.}
+\subsection{\csbh{xintiiSgn}}\label{xintiiSgn}
- One fix is to make sure that the outer conditionals are expanded before the
- inner loop is executed, e.g. this will be the case if the inner loop is
- located inside one of the branches of the conditional.
-
- Another approach is to enclose, if feasible, the inner loop in a group of
- its own.
- \item \emph{if the replacement text closes a group (e.g. from a |&| inside an
- alignment), the conditionals will lose their ascribed meanings and end up
- possibly undefined, depending whether there is some outer loop whose
- execution started before the opening of the group.}
-
- The fix is to arrange things so that the conditionals are expanded
- before \TeX\ encounters the closing-group token.
- \end{itemize}
-\end{framed}

-\subsection{ \csbh{xintBreakFor}, \csbh{xintBreakForAndDo}}
-\label{xintBreakFor}\label{xintBreakForAndDo}
-
-One may immediately terminate an \csbxint{For} or \csbxint{For*} loop with
-\csbxint{BreakFor}.
-
-\begin{framed}
- As it acts by clearing up all the rest of the replacement text when
- encountered, it will not work from inside some |\if...\fi| without
- suitable |\expandafter| or swapping technique.
-
- Also it can't be used from inside braces as from there it can't see the end
- of the replacement text.
-\end{framed}
-
-There is also \csbxint{BreakForAndDo}. Both are illustrated by various examples
-in the next section which is devoted to ``forever'' loops.

-\subsection{\csbh{xintintegers}, \csbh{xintdimensions}, \csbh{xintrationals}}
-\label{xintegers}\label{xintintegers}
-\label{xintdimensions}\label{xintrationals}
-
-If the list argument to \csbxint{For} (or \csbxint{For*}, both are equivalent in
-this context) is \csbxint{integers} (equivalently \csbxint{egers}) or more
-generally \csbxint{integers}|[||start|\allowbreak|+|\allowbreak|delta||]|
-(\emph{the whole within braces}!)%
-%
-\footnote{the |start+delta| optional specification may have extra spaces
- around the plus sign of near the square brackets, such spaces are
- removed. The same applies with \csa{xintdimensions} and
- \csa{xintrationals}.},
-%
-then \csbxint{For} does an infinite iteration where
-|#1| (or |#2|, \dots, |#9|) will run through the arithmetic sequence of (short)
-integers with initial value |start| and increment |delta| (default values:
-|start=1|, |delta=1|; if the optional argument is present it must contains both
-of them, and they may be explicit integers, or macros or count registers). The
-|#1| (or |#2|, \dots, |#9|) will stand for |\numexpr <opt sign><digits>\relax|,
-and the litteral representation as a string of digits can thus be obtained as
-\fbox{\csa{the\#1}} or |\number#1|. Such a |#1| can be used in an |\ifnum| test
-with no need to be postfixed with a space or a |\relax| and one should
-\emph{not} add them.
-
-If the list argument is \csbxint{dimensions} or more generally
-\csbxint{dimensions}|[||start|\allowbreak|+|\allowbreak|delta||]| (\emph{within
- braces}!), then
-\csbxint{For} does an infinite iteration where |#1| (or |#2|, \dots, |#9|) will
-run through the arithmetic sequence of dimensions with initial value
-|start| and increment |delta|. Default values: |start=0pt|, |delta=1pt|; if
-the optional argument is present it must contain both of them, and they may
-be explicit specifications, or macros, or dimen registers, or length macros
-in \LaTeX{} (the stretch and shrink components will be discarded). The |#1|
-will be |\dimexpr <opt sign><digits>sp\relax|, from which one can get the
-litteral (approximate) representation in points via |\the#1|. So |#1| can be
-used anywhere \TeX{} expects a dimension (and there is no need in conditionals
-to insert a |\relax|, and one should \emph{not} do it), and to print its value
-one uses \fbox{\csa{the\#1}}. The chosen representation guarantees exact
-incrementation with no rounding errors accumulating from converting into
-points at each step.
-
-
-
-
-
-
-If the list argument to \csbxint{For} (or \csbxint{For*}) is \csbxint{rationals}
-or more generally
-\csbxint{rationals}|[||start|\allowbreak|+|\allowbreak|delta||]| (\emph{within
- braces}!), then \csbxint{For} does an infinite iteration where |#1| (or |#2|,
-\dots, |#9|) will run through the arithmetic sequence of \xintfracname fractions
-with initial value |start| and increment |delta| (default values: |start=1/1|,
-|delta=1/1|). This loop works \emph{only with \xintfracname loaded}. if the
-optional argument is present it must contain both of them, and they may be given
-in any of the formats recognized by \xintfracname (fractions, decimal
-numbers, numbers in scientific notations, numerators and denominators in
-scientific notation, etc...) , or as macros or count registers (if they are
-short integers). The |#1| (or |#2|, \dots, |#9|) will be an |a/b| fraction
-(without a |[n]| part), where
-the denominator |b| is the product of the denominators of
-|start| and |delta| (for reasons of speed |#1| is not reduced to irreducible
-form, and for another reason explained later |start| and |delta| are not put
-either into irreducible form; the input may use explicitely \csa{xintIrr} to
-achieve that).

-\end{everbatim*}
-
-\smallskip The example above confirms that computations are done exactly, and
-illustrates that the two initial (reduced) denominators are not multiplied when
-they are found to be equal. It is thus recommended to input |start| and |delta|
-with a common smallest possible denominator, or as fixed point numbers with the
-same numbers of digits after the decimal mark; and this is also the reason why
-|start| and |delta| are not by default made irreducible. As internally the
-computations are done with numerators and denominators completely expanded, one
-should be careful not to input numbers in scientific notation with exponents in
-the hundreds, as they will get converted into as many zeroes.

-We see here that \csbxint{Trunc} outputs (deliberately) zero as $0$, not (here)
-$0.000$, the idea being not to lose the information that the truncated thing was
-truly zero. Perhaps this behavior should be changed? or made optional? Anyhow
-printing of fixed points numbers should be dealt with via dedicated packages
-such as |numprint| or |siunitx|.\par

-\subsection{\csbh{xintForpair}, \csbh{xintForthree}, \csbh{xintForfour}}\label{xintForpair}\label{xintForthree}\label{xintForfour}

-\csbxint{Forpair} must be followed by either |#1#2|, |#2#3|, |#3#4|, \dots, or

-|#1|, |#2#3#4| or simply |#2|, \dots) and \csbxint{Forfour} (with |#1#2#3#4|
-etc\dots).
-
-Nesting works as long as the macro parameters are distinct among |#1|, |#2|,

-\csa{xintFor(pair,three,four)} can be used in another one with no constraint
-about using distinct macro parameters.

-
-\csa{xintAssign}\meta{braced things}\csa{to}%
-\meta{as many cs as they are things} %\ntype{{(f$\to$\lowast [x)}{\lowast N}}
-%
-defines (without checking if something gets overwritten) the control sequences
-on the right of \csa{to} to expand to the successive tokens or braced items
-located to the left of \csa{to}. \csa{xintAssign} is not an expandable macro.
-
-\fexpan sion is first applied to the material in front of \csa{xintAssign}
-which is fetched as one argument if it is braced. Then the expansion of this
-argument is examined and successive items are assigned to the macros following
-|\to|. There must be exactly as many macros as items. No check is done. The
-macro assignments are done with removal of one level of brace pairs from each
-item.
-
-After the initial \fexpan sion, each assigned (brace-stripped) item will be
-expanded according to the setting of the optional parameter.
-
-For example |\xintAssign [e]...| means that all assignments are done using
-|\edef|. With |[f]| the assignments will be made using
-\hyperref[fdef]{\ttfamily\char92fdef}. The default is simply to make the
-definitions with |\def|, corresponding to an empty optional paramter |[]|.
-Possibilities for the optional parameter are: |[], [g], [e], [x], [o], [go],
-[oo], [goo], [f], [gf]|. For example |[oo]| means a double expansion.

-\meaning\SevenToThePowerThirteen\par
-\end{everbatim*}
-
-Two special cases:
-\begin{itemize}[nosep]
-\item if after this initial expansion no brace is found immediately after
- \csa{xintAssign}, it is assumed that there is only one control sequence
- following |\to|, and this control sequence is then defined via |\def| (or
- what is set-up by the optional parameter) to expand to the material between
- \csa{xintAssign} and \csa{to}.
-\item if the material between \csa{xintAssign} and |\to| is enclosed in two
- brace pairs, the first brace pair is removed, then the \fexpan sion is
- immediately stopped by the inner brace pair, hence \csa{xintAssign} now
- finds a unique item and thus defines only a single macro to be this item,
- which is now stripped of the second pair of braces.
-\end{itemize}
-
-
-\emph{Note:} prior to release |1.09j|, |\xintAssign| did an |\edef| by default
-for each item assignment but it now does |\def| corresponding to no or empty
-optional parameter.
-
-It is allowed for the successive braced items to be separated by spaces. They
-are removed during the assignments. But if a single macro is defined (which
-happens if the argument after \fexpan sion does not start with a brace),
-naturally the scooped up material has all intervening spaces, as it is
-considered a
-single item. But an upfront initial space will have been absorbed by \fexpan
-sion.

-
-\csa{xintAssignArray} admits an optional parameter, for example

-\section{Macros of the \xintcorename package}
-\label{sec:core}
-
-\localtableofcontents
-
-Prior to release |1.1| the macros which are now included in the separate
-package \xintcorename were part of \xintname. Package \xintcorename is
-automatically loaded by \xintname.\IMPORTANT\
-
-\xintcorename provides the five basic arithmetic operations on big integers:
-addition, subtraction, multiplication, division and powers. Division may be
-either rounded (\csbxint{iiDivRound}) (the rounding of |0.5| is |1| and the
-one of |-0.5| is |-1|) or Euclidean (\csbxint{iiQuo}) (which for positive
-operands is the same as truncated division), or truncated (\csbxint{iiDivTrunc}).
-
-In the description of the macros the \texttt{\n} and \texttt{\m} symbols stand
-for explicit (big) integers within braces or more generally any control
-sequence (possibly within braces) \hyperref[ssec:expansions]{\fexpan ding} to
-such a big integer.
-
-The macros with a single |i| in their names parse their arguments
-automatically through \hyperref[xintiNum]{\string\xintNum}. This type of
-expansion applied to an argument is signaled by a
-\textcolor[named]{PineGreen}{\Numf} in the margin. The accepted input format
-is then a sequence of plus and minus signs, followed by some string of zeroes,
-followed by digits.
-
-If \xintfracname additionally to \xintcorename is loaded, \csbxint{Num}
-becomes a synonym to \csbxint{TTrunc}; this means that
-arbitrary fractions will be accepted as arguments of the
-macros with a single |i| in their names, but get truncated to integers before
-further processing. The format of the output will be as with only \xintname
-loaded. The only extension is in allowing a wider variety of inputs.
-
-The macros with |ii| in their names have arguments which will only be \fexpan
-ded, but will not be parsed via \hyperref[xintiNum]{\string\xintNum}.
-Arguments of this type are signaled by the margin annotation
-\textcolor[named]{PineGreen}{\emph{f}}. For such big integers only one minus
-sign and no plus sign, nor leading zeros, are accepted. |-0| is not valid in
-this strict input format. Loading \xintfracname does not bring any
-modification to these macros whether for input or output.
-
-The letter \texttt{x} (with margin annotation
-\textcolor[named]{PineGreen}{\numx}) stands for something which will be
-inserted in-between a |\numexpr| and a |\relax|. It will thus be completely
-expanded and must give an integer obeying the \TeX{} bounds. Thus, it may be
-for example a count register, or itself a \csa{numexpr} expression, or just a
-number written explicitely with digits or something like |4*\count 255 + 17|,
-etc...
-
-For the rules regarding direct use of count registers or \csa{numexpr}
-expression, in the arguments to the package macros, see the
-\autoref{sec:useofcount} section.
-
-\begin{framed}
- The macros \csbxint{iAdd}, \csbxint{iMul}, \dots, respectively
- \csbxint{iiAdd}, \csbxint{iiMul}, \dots from \xintcorename are guaranteed to
- always output an integer without a trailing |/B| or |[N]|. The |ii| macros
- have the lesser overhead; the |i| macros can be used (if \xintfracname is
- loaded), with fractions, as they will truncate their arguments to integers.
- But their output format remains unmodified: integers with no fraction slash
- nor |[N]|.
-\end{framed}
-
-The {\color[named]{PineGreen}$\star$}'s in the margin are there to remind of
-the complete expandability, even \fexpan dability of the macros, as discussed
-in \autoref{ssec:expansions}.
-
-
-\subsection{\csbh{xintNum}, \csbh{xintiNum}}\label{xintiNum}
-
-|\xintNum|\n\etype{f} removes chains of plus or minus signs, followed by
-zeroes. %

- {=\xintNum{+---++----+--000000000367941789479}}}
-
-All \xintname macros with a single |i| in their names, such as \csbxint{iAdd},
-\csbxint{iMul} apply \csbxint{Num} to their arguments.
-
-When \xintfracname is loaded, \csbxint{Num} becomes a synonym to
-\csbxint{TTrunc}. And \csbxint{iNum} preserved the original integer only
-meaning.
-
-\subsection{\csbh{xintSgn}, \csbh{xintiiSgn}}\label{xintiiSgn}
-
|\xintiiSgn|\n\etype{f} returns 1 if the number is positive, 0 if it is zero
-and -1 if it is negative. It skips the \csbxint{Num} overhead.
+and -1 if it is negative.
-\csbxint{Sgn}\etype{\Numf} is the variant using \csbxint{Num} and getting
-extended by \xintfracname to fractions.
+\subsection{\csbh{xintiiOpp}}\label{xintiiOpp}
-\subsection{\csbh{xintiOpp}, \csbh{xintiiOpp}}\label{xintiOpp}\label{xintiiOpp}
+|\xintiiOpp|\n\etype{f} outputs the opposite |-N| of the number |N|.
-|\xintiOpp|\n\etype{\Numf} return the opposite |-N| of the number |N|.
-
-\csa{xintiiOpp} is the strict integer-only variant which skips
-the \csbxint{Num} overhead.\etype{f}
-
Important note: an input such as |-\foo| is not legal, generally speaking, as
argument to the macros of the \xintname bundle (except, naturally in
\csbxint{expr}-essions). The reason is that the minus sign stops the \fexpan
sion done during parsing of the inputs. One must use the syntax
-|\xintiiOpp{\foo}| or |\xintiOpp{\foo}| when one wants to pass |-\foo| as
+|\xintiiOpp{\foo}| if one wants to pass |-\foo| as
argument to other macros.
-\subsection{\csbh{xintiAbs}, \csbh{xintiiAbs}}\label{xintiAbs}\label{xintiiAbs}
+\subsection{\csbh{xintiiAbs}}\label{xintiiAbs}

+\subsection{\csbh{xintiiAdd}}\label{xintiiAdd}
-\subsection{\csbh{xintiiFDg}}\label{xintFDg}\label{xintiiFDg}
+|\xintiiAdd|\n\m\etype{ff} computes the sum of the two (big) integers.
-|\xintiiFDg|\n\etype{f} returns the first digit (most significant) of the
-decimal expansion. It skips the overhead of parsing via \csbxint{Num}. The
-variant \csa{xintFDg}\etype{\Numf} uses |\xintNum| and gets extended by
-\xintfracname.
+\subsection{\csbh{xintiiCmp}}\label{xintiiCmp}
-\subsection{\csbh{xintiiLDg}}\label{xintLDg}\label{xintiiLDg}
-
-|\xintiiLDg|\n\etype{f} returns the least significant digit. When the number

Since |1.1 2014/10/28| the core arithmetic macros have been moved to a separate
package \xintcorename, which is automatically loaded by \xintname.
+Only the \csbxint{iiSum}, \csbxint{iiPrd}, \csbxint{iiSquareRoot},
+\csbxint{iiPFactorial}, \csbxint{iiBinomial} genuinely add to the arithmetic

+For all macros described here for which it makes sense, package \xintfracname
+defines a similar one without |ii| in its name. This will handle more general
+inputs: decimal, scientific numbers, fractions. The |ii| macros provided here
+by \xintname can be nested inside macros of \xintfracname but the opposite
+does not apply, because the output format of the \xintfracname macros, even
+for representing integers, is not understood by the |ii| macros. The «Boolean

+needed if the input is obtained as a nested chain of \xintfracname macros for
+example.

-\begin{itemize}
-\item if |N| is
- positive or zero, |Q| and |R| are the quotient and remainder in

-\begin{framed}
- This package loads automatically \xintname and \xintcorename, hence all
- macros described in \autoref{sec:xint} and \autoref{sec:core} are
- available. Note that macros of those packages whose names contain |ii| are
- for integers only, not fractions. Those with a single |i| accept fractions

+otherwise.
-\def\x{|{x}|}
+\subsection{\csbh{xintOR}}\label{xintOR}
-This package was first included in release |1.03| (|2013/04/14|) of the
-\xintname bundle. The general rule of the bundle that each macro first expands
-(what comes first, fully) each one of its arguments applies.
+|\xintOR{f}{g}|\etype{ff} returns \dtt{1} if |f!=0| or |g!=0| and \dtt{0}
+otherwise.
-|f|\ntype{\Ff} stands for an integer or a fraction (see \autoref{sec:inputs}
-for the accepted input formats) or something which expands to an integer or
-fraction. It is possible to use in the numerator or the denominator of |f| count
-registers and even expressions with infix arithmetic operators, under some rules
-which are explained in the \autoref{sec:useofcount} section.
+\subsection{\csbh{xintXOR}}\label{xintXOR}
-As in the \hyperref[sec:xint]{xint.sty} documentation, |x|\ntype{\numx}
-stands for something which will internally be embedded in a \csa{numexpr}.
-It
-may thus be a count register or something like |4*\count 255 + 17|, etc..., but
-must expand to an integer obeying the \TeX{} bound.
+|\xintXOR{f}{g}|\etype{ff} returns \dtt{1} if exactly one of |f| or |g|
+is true (i.e. non-zero), else \dtt{0}.
-The fraction format on output is the scientific notation for the `float' macros,
-and the |A/B[n]| format for all other fraction macros, with the exception of
-\csbxint{Trunc}, {\color{blue}\string\xint\-Round} (which produce decimal
-numbers) and \csbxint{Irr}, \csbxint{Jrr}, \csbxint{RawWithZeros} (which returns
-an |A/B| with no trailing |[n]|, and prints the |B| even if it is |1|), and
-\csbxint{PRaw} which does not print the |[n]| if |n=0| or the |B| if |B=1|.
+\subsection{\csbh{xintANDof}}\label{xintANDof}
-To be certain to print an integer output without trailing |[n]| nor fraction
-slash, one should use either |\xintPRaw {\xintIrr {f}}| or |\xintNum {f}| when
-it is already known that |f| evaluates to a (big) integer. For example
-|\xintPRaw {\xintAdd {2/5}{3/5}}| gives a perhaps disappointing
-\dtt{\xintPRaw {\xintAdd {2/5}{3/5}}}

-whereas |\xintPRaw {\xintIrr {\xintAdd
- {2/5}{3/5}}}| returns \dtt{\xintPRaw {\xintIrr {\xintAdd
- {2/5}{3/5}}}}. As we knew the result was an integer we could have used
-|\xintNum {\xintAdd {2/5}{3/5}}=|\xintNum {\xintAdd {2/5}{3/5}}.
+\csa{xintANDof}|{{a}{b}{c}...}|\etype{f{$\to$}\lowast f} returns \dtt{1} if
+all are true (i.e. non zero) and \dtt{0} otherwise. The list argument may be a
+macro, it (or rather its first token) is \fexpan ded first to deliver its
+items.
-Some macros (such as \csbxint{iTrunc}, \csbxint{iRound}, and \csbxint{iFac})

+\csa{xintORof}|{{a}{b}{c}...}|\etype{f{$\to$}\lowast f} returns \dtt{1} if at
+least one is true (i.e. does not vanish), else it produces \dtt{0}. The list
+argument may be a macro, it is \fexpan ded first.

+The list argument may be a macro, it is \fexpan ded first.
-The macro\etype{f} from \xintname is made a synonym to \csbxint{TTrunc}.%

-The original (which

-\csbxint{iNum}.
-It is imprudent to apply \csa{xintNum} to numbers with a large
-power of ten given either in scientific notation or with the |[n]| notation,
-as the macro will according to its definition add all the needed zeroes to
-produce an explicit integer in strict format.

-\csa{xintifInt}|{f}{YES branch}{NO branch}|\etype{\Ff nn} expandably chooses

+\hyperref[xintNumFrac]{\string\xintNum} and
+\hyperref[xintLenFrac]{\string\xintLen}. As explained in \autoref{ssec:inputs}

+Hence, to use such an |ii|-macro with an output from an \xintfracname macro,

+plus the absolute value of |n| and minus one (an integer input as |N| is
+internally represented in a form equivalent to |N/1[0]| so the minus one means
+that the extended \csa{xintLen} behaves the same as the original for
+integers).

+\xintLen{-1e3/5.425} (\xintRaw {-1e3/5.425})\par
+\end{everbatim*}
+The length is computed on the |A/B[n]| which would have been returned by
+\csbxint{Raw}, as illustrated by the last example above.
+
+|\xintLen| is only for use with such (scientific) numbers or fractions. See
+also \csbxint{NthElt} from \xinttoolsname. See also \csbxint{Length} (which

+\xinttoolsname, which has none of the \xintname facilities regarding big
+numbers. Whenever relevant release |1.09h| has made the macros |\long| so they
+accept |\par| tokens on input.
+
+The completely expandable utilities (up to \csbxint{iloop}) are documented
+first, then the non expandable utilities.
+
+A brief overview is in \autoref{sec:sometoolsutils} and \autoref{sec:examples}

+tokens) are gobbled. This macro is mainly thought out for use on a \meta{list}

+It expands in two steps, and if the goal is to apply it to the

+ The spaces here at the start and end of the output come from the braced

+\subsection{\csbh{xintCSVtoList}}
+\label{xintCSVtoList}
+\label{xintCSVtoListNoExpand}
+
+
+\csa{xintCSVtoList}|{a,b,c...,z}|\etype{f} returns |{a}{b}{c}...{z}|. A
+\emph{list} is by
+convention in this manual simply a succession of tokens, where each braced thing
+will count as one item (``items'' are defined according to the rules of \TeX{}
+for fetching undelimited parameters of a macro, which are exactly the same rules
+as for \LaTeX{} and macro arguments [they are the same things]). The word
+`list' in `comma separated list of items' has its usual linguistic meaning,
+and then an ``item'' is what is delimited by commas.
+
+So \csa{xintCSVtoList} takes on input a `comma separated list of items' and
+converts it into a `\TeX{} list of braced items'. The argument to
+|\xintCSVtoList| may be a macro: it will first be
+\hyperref[ssec:expansions]{\fexpan ded}. Hence the item before the first comma,
+if it is itself a macro, will be expanded which may or may not be a good thing.
+A space inserted at the start of the first item serves to stop that expansion
+(and disappears). The macro \csbxint{CSVtoListNoExpand}\etype{n} does the same
+job without
+the initial expansion of the list argument.
+
+Apart from that no expansion of the items is done and the list items may thus be
+completely arbitrary (and even contain perilous stuff such as unmatched |\if|
+and |\fi| tokens).
+
+Contiguous spaces and tab characters, are collapsed by \TeX{}
+into single spaces. All such spaces around commas%
+%
+\footnote{and multiple space tokens are not a problem; but those at the
+ top level (not hidden inside braces) \emph{must} be of character code
+ |32|.}
+%
+\fbox{are removed}, as well as
+the spaces at the start and the spaces at the end of the list.%
+%
+\footnote{let us recall that this is all done completely expandably...
+ There is absolutely no alteration of any sort of the item apart from
+ the stripping of initial and final space tokens (of character code
+ |32|) and brace removal if and only if the item apart from intial and
+ final spaces (or more generally multiple |char 32| space tokens) is
+ braced.}
+%
+The items may contain explicit |\par|'s or
+empty lines (converted by the \TeX{} input parsing into |\par| tokens).

+
+One sees on this example how braces protect commas from
+sub-lists to be perceived as delimiters of the top list. Braces around an entire
+item are removed, even when surrounded by spaces before and/or after. Braces for
+sub-parts of an item are not removed.
+
+We observe also that there is a slight difference regarding the brace stripping
+of an item: if the braces were not surrounded by spaces, also the initial and
+final (but no other) spaces of the \emph{enclosed} material are removed. This is
+the only situation where spaces protected by braces are nevertheless removed.
+
+From the rules above: for an empty argument (only spaces, no braces, no comma)
+the output is
+\dtt{\expandafter\detokenize\expandafter{\romannumeral0\xintcsvtolist { }}}
+(a list with one empty item),
+for ``|<opt. spaces>{}<opt.
+spaces>|'' the output is
+\dtt{\expandafter\detokenize\expandafter
+ {\romannumeral0\xintcsvtolist { {} }}}
+(again a list with one empty item, the braces were removed),
+for ``|{ }|'' the output is
+\dtt{\expandafter\detokenize\expandafter
+ {\romannumeral0\xintcsvtolist {{ }}}}
+(again a list with one empty item, the braces were removed and then
+the inner space was removed),
+for ``| { }|'' the output is
+\dtt{\expandafter\detokenize\expandafter
+{\romannumeral0\xintcsvtolist { { }}}} (again a list with one empty item, the initial space served only to stop the expansion, so this was like ``|{ }|'' as input, the braces were removed and the inner space was stripped),
+for ``\texttt{\ \{\ \ \}\ }'' the output is
+\dtt{\expandafter\detokenize\expandafter
+{\romannumeral0\xintcsvtolist { { } }}} (this time the ending space of the first
+item meant that after brace removal the inner spaces were kept; recall though
+that \TeX{} collapses on input consecutive blanks into one space token),
+for ``|,|'' the output consists of two consecutive
+empty items
+\dtt{\expandafter\detokenize\expandafter{\romannumeral0\xintcsvtolist
+ {,}}}. Recall that on output everything is braced, a |{}| is an ``empty''
+item.
+%
+Most of the above is mainly irrelevant for every day use, apart perhaps from the
+fact to be noted that an empty input does not give an empty output but a
+one-empty-item list (it is as if an ending comma was always added at the end of
+the input).

+The results above were automatically displayed using \TeX's primitive
+\csa{meaning}, which adds a space after each control sequence name. These spaces
+are not in the actual braced items of the produced lists. The first items |\a|
+and |\if| were either preceded by a space or braced to prevent expansion. The
+macro \csa{xintCSVtoListNoExpand} would have done the same job without the
+initial expansion of the list argument, hence no need for such protection but if
+|\y| is defined as |\def\y{\a,\b,\c,\d,\e}| we then must do:
+%
+\leftedline{|\expandafter\xintCSVtoListNoExpand\expandafter {\y}|} Else, we

+\leftedline{|->|\dtt{\expandafter\detokenize\expandafter

+Again these spaces are an artefact from the use in the source of the document of
+\csa{meaning} (or rather here, \csa{detokenize}) to display the result of using
+\csa{xintCSVtoListNoExpand} (which is done for real in this document
+source).
+
+For the similar conversion from comma separated list to braced items list, but

+If |x=0|,

+together as a succession of braced items (if |\macro| is defined to start with a
+space, the space will be gobbled and the |\macro| will not be expanded; it is
+allowed to have its own arguments, the list items serve as last arguments to

+implicit groups make standard loops constructs usually fail. In such situation
+it is often not wished that the new list elements be braced, see
+\csbxint{ApplyUnbraced}. The |\macro| does not have to be expandable:
+|\xintApply| will try to expand it, the expansion may remain partial.
+
+The \meta{list} may
+itself be some macro expanding (in the previously described way) to the list of
+tokens to which the macro |\macro| will be applied. For example, if the
+\meta{list} expands to some positive number, then each digit will be replaced by
+the result of applying |\macro| on it. %

+ 9-#1\relax}|} %
+%
+\leftedline{|\xintApply\macro{\xintiiFac
+ {20}}|\dtt{=\xintApply\macro{\xintiiFac {20}}}}
+
+The macro \csa{xintApplyNoExpand}\etype{fn} does the same job without the first
+initial expansion which gave the \meta{list} of braced tokens to which |\macro|
+is applied.
+
+\subsection{\csbh{xintApplyUnbraced}}\label{xintApplyUnbraced}
+
+
+\csa{xintApplyUnbraced}|{\macro}|\marg{list}\etype{ff} is like \csbxint{Apply}.
+The difference is that after having expanded its list argument, and applied
+|\macro| in turn to each item from the list, it reassembles the outputs without
+enclosing them in braces. The net effect is the same as doing
+%
+\leftedline{|\xintListWithSep {}{\xintApply {\macro}|\marg{list}|}|} This is
+useful for preparing a macro which will itself define some other macros or make
+assignments, as the scope will not be limited by brace pairs.

+The macro \csa{xintApplyUnbracedNoExpand}\etype{fn} does the same job without

+
+\subsection{\csbh{xintSeq}}\label{xintSeq}
+
+\csa{xintSeq}|[d]{x}{y}|\etype{{{\upshape[\numx]}}\numx\numx} generates
+expandably |{x}{x+d}...| up to and possibly including |{y}| if |d>0| or down
+to and including |{y}| if |d<0|. Naturally |{y}| is omitted if |y-x| is not a
+multiple of |d|. If |d=0| the macro returns |{x}|. If |y-x| and |d| have
+opposite signs, the macro returns nothing. If the optional argument |d| is
+omitted it is taken to be the sign of |y-x|. Hence |\xintSeq {1}{0}| is not
+empty but |{1}{0}|. But |\xintSeq [1]{1}{0}| is empty.
+
+
+The arguments |x| and |y| are expanded inside a |\numexpr| so they may be
+count registers or a \LaTeX{} |\value{countername}|, or arithmetic with such
+things.

+\end{everbatim*}
+
+When the macro is used without the optional argument |d|, it can only generate
+up to about $5000$ numbers\IMPORTANT, the precise value depends upon some
+\TeX{} memory parameter (input save stack).
+
+With the optional argument |d| the macro proceeds differently (but less
+efficiently) and does not stress the input save stack.

+\label{xintloop}
+\label{xintbreakloop}
+\label{xintbreakloopanddo}
+\label{xintloopskiptonext}
+
+|\xintloop|\meta{stuff}|\if<test>...\repeat|\retype{} is an expandable loop
+compatible with nesting. However to break out of the loop one almost always need
+some un-expandable step. The cousin \csbxint{iloop} is \csbxint{loop} with an
+embedded expandable mechanism allowing to exit from the loop. The iterated
+macros may contain |\par| tokens or empty lines.
+
+If a sub-loop is to be used all the material from the start of the main loop and
+up to the end of the entire subloop should be braced; these braces will be
+removed and do not create a group. The simplest to allow the nesting of one or
+more sub-loops is to brace everything between \csa{xintloop} and \csa{repeat},
+being careful not to leave a space between the closing brace and |\repeat|.
+
+As this loop and \csbxint{iloop} will primarily be of interest to experienced
+\TeX{} macro programmers, my description will assume that the user is
+knowledgeable enough. Some examples in this document will be perhaps more
+illustrative than my attemps at explanation of use.
+
+One can abort the loop with \csbxint{breakloop}; this should not be used inside
+the final test, and one should expand the |\fi| from the corresponding test
+before. One has also \csbxint{breakloopanddo} whose first argument will be
+inserted in the token stream after the loop; one may need a macro such as
+|\xint_afterfi| to move the whole thing after the |\fi|, as a simple
+|\expandafter| will not be enough.
+
+One will usually employ some count registers to manage the exit test from the
+loop; this breaks expandability, see \csbxint{iloop} for an expandable integer
+indexed loop. Use in alignments will be complicated by the fact that cells
+create groups, and also from the fact that any encountered unexpandable material
+will cause the \TeX{} input scanner to insert |\endtemplate| on each encountered
+|&| or |\cr|; thus |\xintbreakloop| may not work as expected, but the situation
+can be resolved via |\xint_firstofone{&}| or use of |\TAB| with |\def\TAB{&}|.
+It is thus simpler for alignments to use rather than \csbxint{loop} either the
+expandable \csbxint{ApplyUnbraced} or the non-expandable but alignment
+compatible \csbxint{ApplyInline}, \csbxint{For} or \csbxint{For*}.
+
+As an example, let us suppose we have two macros |\A|\marg{i}\marg{j} and
+|\B|\marg{i}\marg{j} behaving like (small) integer valued matrix entries, and we
+want to define a macro |\C|\marg{i}\marg{j} giving the matrix product (|i| and
+|j| may be count registers). We will assume that |\A[I]| expands to the number
+of rows, |\A[J]| to the number of columns and want the produced |\C| to act in
+the same manner. The code is very dispendious in use of |\count| registers, not
+optimized in any way, not made very robust (the defined macro can not have the
+same name as the first two matrices for example), we just wanted to quickly
+illustrate use of the nesting capabilities of |\xintloop|.%

+
+\csa{xintiloop}|[start+delta]|\meta{stuff}|\if<test> ... \repeat|\retype{} is a
+completely expandable nestable loop. complete expandability depends naturally on
+the actual iterated contents, and complete expansion will not be achievable
+under a sole \fexpan sion, as is indicated by the hollow star in the margin;
+thus the loop can be used inside an |\edef| but not inside arguments to the
+package macros. It can be used inside an |\xintexpr..\relax|. The
+|[start+delta]| is mandatory, not optional.
+
+This loop benefits via \csbxint{iloopindex} to (a limited access to) the integer
+index of the iteration. The starting value |start| (which may be a |\count|) and
+increment |delta| (\emph{id.}) are mandatory arguments. A space after the
+closing square bracket is not significant, it will be ignored. Spaces inside the
+square brackets will also be ignored as the two arguments are first given to a
+|\numexpr...\relax|. Empty lines and explicit |\par| tokens are accepted.
+
+As with \csbxint{loop}, this tool will mostly be of interest to advanced users.
+For nesting, one puts inside braces all the
+material from the start (immediately after |[start+delta]|) and up to and
+inclusive of the inner loop, these braces will be removed and do not create a
+loop. In case of nesting, \csbxint{outeriloopindex} gives access to the index of
+the outer loop. If needed one could write on its model a macro giving access to
+the index of the outer outer loop (or even to the |nth| outer loop).
+
+The \csa{xintiloopindex} and \csa{xintouteriloopindex} can not be used inside
+braces, and generally speaking this means they should be expanded first when
+given as argument to a macro, and that this macro receives them as delimited
+arguments, not braced ones. Or, but naturally this will break expandability, one
+can assign the value of \csa{xintiloopindex} to some |\count|. Both
+\csa{xintiloopindex} and \csa{xintouteriloopindex} extend to the litteral
+representation of the index, thus in |\ifnum| tests, if it comes last one has to
+correctly end the macro with a |\space|, or encapsulate it in a
+|\numexpr..\relax|.
+
+When the repeat-test of the loop is, for example, |\ifnum\xintiloopindex<10
+\repeat|, this means that the last iteration will be with |\xintiloopindex=10|
+(assuming |delta=1|). There is also |\ifnum\xintiloopindex=10 \else\repeat| to
+get the last iteration to be the one with |\xintiloopindex=10|.
+
+One has \csbxint{breakiloop} and \csbxint{breakiloopanddo} to abort the loop.
+The syntax of |\xintbreakiloopanddo| is a bit surprising, the sequence of tokens
+to be executed after breaking the loop is not within braces but is delimited by
+a dot as in:
+%
+\leftedline{|\xintbreakiloopanddo <afterloop>.etc.. etc... \repeat|}
+%
+The reason is that one may wish to use the then current value of
+|\xintiloopindex| in |<afterloop>| but it can't be within braces at the time it
+is evaluated. However, it is not that easy as |\xintiloopindex| must be expanded
+before, so one ends up with code like this:
+%
+\leftedline
+{|\expandafter\xintbreakiloopanddo\expandafter\macro\xintiloopindex.%|}
+%
+\leftedline{|etc.. etc.. \repeat|}
+%
+As moreover the |\fi| from the test leading to the decision of breaking out of
+the loop must be cleared out of the way, the above should be
+a branch of an expandable conditional test, else one needs something such
+as:
+%
+\leftedline
+{|\xint_afterfi{\expandafter\xintbreakiloopanddo\expandafter\macro\xintiloopindex.}%|}
+%
+\leftedline{|\fi etc..etc.. \repeat|}
+
+There is \csbxint{iloopskiptonext} to abort the current iteration and skip to
+the next, \hyperref[xintiloopskipandredo]{\ttfamily\hyphenchar\font45 \char92
+ xintiloopskip\-and\-redo} to skip to the end of the current iteration and redo
+it with the same value of the index (something else will have to change for this
+not to become an eternal loop\dots ).
+
+Inside alignments, if the looped-over text contains a |&| or a |\cr|, any
+un-expandable material before a \csbxint{iloopindex} will make it fail because
+of |\endtemplate|; in such cases one can always either replace |&| by a macro
+expanding to it or replace it by a suitable |\firstofone{&}|, and similarly for
+|\cr|.
+
+\phantomsection\label{edefprimes}
+As an example, let us construct an |\edef\z{...}| which will define |\z| to be a
+list of prime numbers:
+\begin{everbatim*}
+\begingroup
+\edef\z
+{\xintiloop [10001+2]

+ \else
+ \repeat
+ }% no space here
+ \ifnum \xintiloopindex < 10999 \repeat }%
+\meaning\z\endgroup
+\end{everbatim*}and we should have taken
+some steps to not have a trailing comma, but
+the point was to show that one can do that in an |\edef|\,! See also
+\autoref{ssec:primesII} which extracts from this code its way of testing
+primality.
+
+Let us create an alignment where each row will contain all divisors of its
+first entry.
+Here is the output, thus obtained without any count register:
+\begin{everbatim*}

+\end{multicols}
+\end{everbatim*}
+We wanted this first entry in bold face, but |\bfseries| leads to
+unexpandable tokens, so the |\expandafter| was necessary for |\xintiloopindex|
+and |\xintouteriloopindex| not to be confronted with a hard to digest
+|\endtemplate|. An alternative way of coding:

+\end{framed}
+
+\subsection{\csbh{xintApplyInline}}\label{xintApplyInline}
+
+
+\csa{xintApplyInline}|{\macro}|\marg{list}\ntype{o{\lowast f}} works non
+expandably. It applies the one-parameter |\macro| to the first element of the
+expanded list (|\macro| may have itself some arguments, the list item will be
+appended as last argument), and is then re-inserted in the input stream after
+the tokens resulting from this first expansion of |\macro|. The next item is
+then handled.
+
+This is to be used in situations where one needs to do some repetitive
+things. It is not expandable and can not be completely expanded inside a
+macro definition, to prepare material for later execution, contrarily to what
+\csbxint{Apply} or \csbxint{ApplyUnbraced} achieve.
+
+\begin{everbatim*}
+\def\Macro #1{\advance\cnta #1 , \the\cnta}
+\cnta 0
+0\xintApplyInline\Macro {3141592653}.
+\end{everbatim*}
+The first argument |\macro| does not have to be an expandable macro.
+
+\csa{xintApplyInline} submits its second, token list parameter to an
+\hyperref[ssec:expansions]{\fexpan
+sion}. Then, each \emph{unbraced} item will also be \fexpan ded. This provides
+an easy way to insert one list inside another. \emph{Braced} items are not
+expanded. Spaces in-between items are gobbled (as well as those at the start
+or the end of the list), but not the spaces \emph{inside} the braced items.
+
+\csa{xintApplyInline}, despite being non-expandable, does survive to
+contexts where the executed |\macro| closes groups, as happens inside
+alignments with the tabulation character |&|.
+This tabular provides an example:\par
+\begin{everbatim*}
+\centerline{\normalcolor\begin{tabular}{ccc}
+ $N$ & $N^2$ & $N^3$ \\ \hline
+ \def\Row #1{ #1 & \xintiiSqr {#1} & \xintiiPow {#1}{3} \\ \hline }%
+ \xintApplyInline \Row {\xintCSVtoList{17,28,39,50,61}}
+\end{tabular}}\medskip
+\end{everbatim*}
+
+We see that despite the fact that the first encountered tabulation character in
+the first row close a group and thus erases |\Row| from \TeX's memory,
+|\xintApplyInline| knows how to deal with this.
+
+Using \csbxint{ApplyUnbraced} is an alternative: the difference is that
+this would have prepared all rows first and only put them back into the
+token stream once they are all assembled, whereas with |\xintApplyInline|
+each row is constructed and immediately fed back into the token stream: when
+one does things with numbers having hundreds of digits, one learns that
+keeping on hold and shuffling around hundreds of tokens has an impact on
+\TeX{}'s speed (make this ``thousands of tokens'' for the impact to be
+noticeable).
+
+One may nest various |\xintApplyInline|'s. For example (see the
+\hyperref[float]{table} \vpageref{float}):\par
+\begin{everbatim*}
+\begin{figure*}[ht!]
+ \centering\phantomsection\label{float}
+ \def\Row #1{#1:\xintApplyInline {\Item {#1}}{0123456789}\\ }%
+ \def\Item #1#2{&\xintiiPow {#1}{#2}}%
+ \centeredline {\begin{tabular}{ccccccccccc} &0&1&2&3&4&5&6&7&8&9\\ \hline
+ \xintApplyInline \Row {0123456789}
+ \end{tabular}}
+\end{figure*}
+\end{everbatim*}
+
+One could not move the definition of |\Item| inside the tabular,
+as it would get lost after the first |&|. But this
+works:
+\everb|@
+\begin{tabular}{ccccccccccc}
+ &0&1&2&3&4&5&6&7&8&9\\ \hline
+ \def\Row #1{#1:\xintApplyInline {&\xintiiPow {#1}}{0123456789}\\ }%
+ \xintApplyInline \Row {0123456789}
+\end{tabular}
+|
+
+A limitation is that, contrarily to what one may have expected, the
+|\macro| for an |\xintApplyInline| can not be used to define
+the |\macro| for a nested sub-|\xintApplyInline|. For example,
+this does not work:\par
+\everb|@
+ \def\Row #1{#1:\def\Item ##1{&\xintiiPow {#1}{##1}}%
+ \xintApplyInline \Item {0123456789}\\ }%
+ \xintApplyInline \Row {0123456789} % does not work
+|
+\noindent But see \csbxint{For}.
+
+\subsection{\csbh{xintFor}, \csbh{xintFor*}}\label{xintFor}\label{xintFor*}
+
+\csbxint{For}\ntype{on} is a new kind of for loop.\footnote{first introduced
+ with \xintname |1.09c| of |2013/10/09|.} Rather than using macros
+for encapsulating list items, its behavior is like a macro with parameters:
+|#1|, |#2|, \dots, |#9| are used to represent the items for up to nine levels of
+nested loops. Here is an example:
+%
+\everb|@
+\xintFor #9 in {1,2,3} \do {%
+ \xintFor #1 in {4,5,6} \do {%
+ \xintFor #3 in {7,8,9} \do {%
+ \xintFor #2 in {10,11,12} \do {%
+ $$#9\times#1\times#3\times#2=\xintiiPrd{{#1}{#2}{#3}{#9}}$$}}}}
+|
+\noindent This example illustrates that one does not have to use |#1| as the
+first one:
+the order is arbitrary. But each level of nesting should have its specific macro
+parameter. Nine levels of nesting is presumably overkill, but I did not know
+where it was reasonable to stop. |\par| tokens are accepted in both the comma
+separated list and the replacement text.
+
+\begin{framed}
+ \TeX nical notes:
+
+\begin{itemize}
+ \item The |#1| is replaced in the iterated-over text exactly as in general
+ \TeX\ macros or \LaTeX\ commands. This spares the user quite a few
+ |\expandafter|'s or other tricks needed with loops which have the
+ values encapsulated in macros, like \LaTeX's |\@for| and |\@tfor|.
+
+ \item \csa{xintFor} (and \csa{xintFor*}) isn't purely expandable: one can
+ not use it inside an |\edef|. But it may be used, as will be shown in
+ examples, in some contexts such as \LaTeX's |tabular| which are usually
+ hostile to non-expandable loops.
+
+ \item \csa{xintFor} (and \csa{xintFor*}) does some assignments prior to
+ executing each iteration of the replacement text, but it acts purely
+ expandably after the last iteration, hence if for example the replacement
+ text ends with a |\\|, the loop can be used insided a tabular and be
+ followed by a |\hline| without creating the dreaded ``|Misplaced
+ \noalign|'' error.
+
+ \item It does not create groups.
+
+ \item It makes no global assignments.
+
+ \item The iterated replacement text may close a group which was opened even
+ before the start of the loop (typical example being with |&| in
+ alignments).
+\begin{everbatim*}
+\begin{tabular}{rccccc}
+ \hline
+ \xintFor #1 in {A, B, C} \do {%
+ #1:\xintFor #2 in {a, b, c, d, e} \do {&($ #2 \to #1 $)}\\ }%
+ \hline
+\end{tabular}
+\end{everbatim*}
+
+ \item There is no facility provided which would give access to a count of
+ the number of iterations as it is technically not easy to do so it in a
+ way working with nested loops while maintaining the ``expandable after

+ \LaTeX{} counter or macro at each iteration, if needed.
+
+ \item A |\macro| whose definition uses internally an \csbxint{For} loop
+ may be used inside another \csbxint{For} loop even if the two loops both
+ use the same macro parameter. The loop definition inside |\macro|

+
+ \item \csbxint{For} is for comma separated values and \csbxint{For*} for
+ lists of braced items; their respective expansion policies differ. They
+ are described later.
+\end{itemize}
+\unskip
+\end{framed}
+
+\noindent Regarding \csbxint{For}:
+\begin{itemize}[nosep, listparindent=\leftmarginiii]
+\item the spaces between the various declarative elements are all optional,
+\item in the list of comma separated values, spaces around the commas or at
+ the start and end are ignored,
+\item if an item must contain itself its own commas, then it should
+ be braced, and the braces will be removed before feeding the iterated-over
+ text,
+\item the list may be a macro, it is expanded only once,
+\item items are not pre-expanded. The first item should be braced or start
+ with a space if the list is explicit and the item should not be
+ pre-expanded,
+\item empty items give empty |#1|'s in the replacement text, they are not
+ skipped,
+\item an empty list executes once the replacement text with an empty parameter
+ value,
+\item the list, if not a macro, \fbox{must be braced.}
+\end{itemize}
+
+\noindent Regarding \csbxint{For*}:\ntype{{\lowast f}n}
+\begin{itemize}[nosep, listparindent=\leftmarginiii]
+\item it handles lists of braced items (or naked tokens),
+\item it \hyperref[ssec:expansions]{\fexpan ds} the list,
+\item and more generally it \hyperref[ssec:expansions]{\fexpan ds} each naked
+ token encountered
+ before assigning the |#1| values (gobbling spaces in the process);
+ this
+ makes it easy to simulate concatenation of multiple lists|\x|, |\y|:
+ if |\x| expands to |{1}{2}{3}| and |\y| expands to |{4}{5}{6}| then |{\x\y}|
+ as argument to |\xintFor*| has the same effect as |{{1}{2}{3}{4}{5}{6}}|.
+
+ For a further illustration see the use of |\xintFor*| at the end of
+ \autoref{ssec:fibonacci}.
+\item spaces at the start, end, or in-between items are gobbled (but naturally
+ not the spaces inside \emph{braced} items),
+\item except if the list argument is a macro (with no parameters), \fbox{it
+ must be braced.},
+\item an empty list leads to an empty result.
+\end{itemize}
+
+The macro \csbxint{Seq} which generates arithmetic sequences is to be used
+with \csbxint{For*} as its output consists of successive braced numbers (given
+as digit tokens).
+\begin{everbatim*}
+\xintFor* #1 in {\xintSeq [+2]{-7}{+2}}\do {stuff
+ with #1\xintifForLast{\par}{\newline}}
+\end{everbatim*}
+
+
+When nesting \csa{xintFor*} loops, using \csa{xintSeq} in the inner loops is
+inefficient, as the arithmetic sequence will be re-created each time. A more
+efficient style is:
+%
+\begin{everbatim}
+ \edef\innersequence {\xintSeq[+2]{-50}{50}}%
+ \xintFor* #1 in {\xintSeq {13}{27}} \do
+ {\xintFor* #2 in \innersequence \do {stuff with #1 and #2}%
+ .. some other macros .. }
+\end{everbatim}
+
+This is a general remark applying for any nesting of loops, one should avoid
+recreating the inner lists of arguments at each iteration of the outer loop.
+
+
+When the loop is defined inside a macro for later execution the |#| characters
+must be doubled.%
+%
+\footnote{sometimes what seems to be a macro argument isn't really; in
+ \csa{raisebox\{1cm\}\{}\csa{xintFor \#1 in \{a,b,c\} }\csa{do
+ \{\#1\}\}} no doubling should be done.}
+%
+For example:
+%
+\begin{everbatim*}
+\def\T{\def\z {}%
+ \xintFor* ##1 in {{u}{v}{w}} \do {%
+ \xintFor ##2 in {x,y,z} \do {%
+ \expandafter\def\expandafter\z\expandafter {\z\sep (##1,##2)} }%
+ }%
+}%
+\T\def\sep {\def\sep{, }}\z
+\end{everbatim*}
+
+Similarly when the replacement text
+of |\xintFor| defines a macro with parameters, the macro character |#| must be
+doubled.
+
+
+The iterated macros as well as the list items are allowed to contain explicit
+|\par| tokens.

+if the
+\csbxint{For}

+
+Designed to work as expected under nesting (but see frame next.) Don't forget
+an empty brace pair |{}| if a branch is to do nothing. May be used multiple

+
+\begin{framed}
+ \noindent Pay attention to these implementation features:
+ \begin{itemize}[nosep, listparindent=\leftmarginiii]
+ \item \emph{if an inner \csbxint{For} loop is positioned before the
+ \csb{xintifForFirst} or \csb{xintifForLast} of the outer loop it will
+ contaminate their settings. This applies also naturally if the inner loop
+ arises from the expansion of some macro located before the outer
+ conditionals.}
+
+ One fix is to make sure that the outer conditionals are expanded before the
+ inner loop is executed, e.g. this will be the case if the inner loop is
+ located inside one of the branches of the conditional.
+
+ Another approach is to enclose, if feasible, the inner loop in a group of
+ its own.
+ \item \emph{if the replacement text closes a group (e.g. from a |&| inside an
+ alignment), the conditionals will lose their ascribed meanings and end up
+ possibly undefined, depending whether there is some outer loop whose
+ execution started before the opening of the group.}
+
+ The fix is to arrange things so that the conditionals are expanded
+ before \TeX\ encounters the closing-group token.

+\subsection{ \csbh{xintBreakFor}, \csbh{xintBreakForAndDo}}
+\label{xintBreakFor}\label{xintBreakForAndDo}
+
+One may immediately terminate an \csbxint{For} or \csbxint{For*} loop with
+\csbxint{BreakFor}.
+
+\begin{framed}
+ As it acts by clearing up all the rest of the replacement text when
+ encountered, it will not work from inside some |\if...\fi| without
+ suitable |\expandafter| or swapping technique.
+
+ Also it can't be used from inside braces as from there it can't see the end
+ of the replacement text.
+\end{framed}
+
+There is also \csbxint{BreakForAndDo}. Both are illustrated by various examples
+in the next section which is devoted to ``forever'' loops.
+
+\subsection{\csbh{xintintegers}, \csbh{xintdimensions}, \csbh{xintrationals}}
+\label{xintegers}\label{xintintegers}
+\label{xintdimensions}\label{xintrationals}
+
+If the list argument to \csbxint{For} (or \csbxint{For*}, both are equivalent in
+this context) is \csbxint{integers} (equivalently \csbxint{egers}) or more
+generally \csbxint{integers}|[||start|\allowbreak|+|\allowbreak|delta||]|
+(\emph{the whole within braces}!)%
+%
+\footnote{the |start+delta| optional specification may have extra spaces
+ around the plus sign of near the square brackets, such spaces are
+ removed. The same applies with \csa{xintdimensions} and
+ \csa{xintrationals}.},
+%
+then \csbxint{For} does an infinite iteration where
+|#1| (or |#2|, \dots, |#9|) will run through the arithmetic sequence of (short)
+integers with initial value |start| and increment |delta| (default values:
+|start=1|, |delta=1|; if the optional argument is present it must contains both
+of them, and they may be explicit integers, or macros or count registers). The
+|#1| (or |#2|, \dots, |#9|) will stand for |\numexpr <opt sign><digits>\relax|,
+and the litteral representation as a string of digits can thus be obtained as
+\fbox{\csa{the\#1}} or |\number#1|. Such a |#1| can be used in an |\ifnum| test
+with no need to be postfixed with a space or a |\relax| and one should
+\emph{not} add them.
+
+If the list argument is \csbxint{dimensions} or more generally
+\csbxint{dimensions}|[||start|\allowbreak|+|\allowbreak|delta||]| (\emph{within
+ braces}!), then
+\csbxint{For} does an infinite iteration where |#1| (or |#2|, \dots, |#9|) will
+run through the arithmetic sequence of dimensions with initial value
+|start| and increment |delta|. Default values: |start=0pt|, |delta=1pt|; if
+the optional argument is present it must contain both of them, and they may
+be explicit specifications, or macros, or dimen registers, or length macros
+in \LaTeX{} (the stretch and shrink components will be discarded). The |#1|
+will be |\dimexpr <opt sign><digits>sp\relax|, from which one can get the
+litteral (approximate) representation in points via |\the#1|. So |#1| can be
+used anywhere \TeX{} expects a dimension (and there is no need in conditionals
+to insert a |\relax|, and one should \emph{not} do it), and to print its value
+one uses \fbox{\csa{the\#1}}. The chosen representation guarantees exact
+incrementation with no rounding errors accumulating from converting into
+points at each step.
+
+
+
+
+
+
+If the list argument to \csbxint{For} (or \csbxint{For*}) is \csbxint{rationals}
+or more generally
+\csbxint{rationals}|[||start|\allowbreak|+|\allowbreak|delta||]| (\emph{within
+ braces}!), then \csbxint{For} does an infinite iteration where |#1| (or |#2|,
+\dots, |#9|) will run through the arithmetic sequence of \xintfracname fractions
+with initial value |start| and increment |delta| (default values: |start=1/1|,
+|delta=1/1|). This loop works \emph{only with \xintfracname loaded}. if the
+optional argument is present it must contain both of them, and they may be given
+in any of the formats recognized by \xintfracname (fractions, decimal
+numbers, numbers in scientific notations, numerators and denominators in
+scientific notation, etc...) , or as macros or count registers (if they are
+short integers). The |#1| (or |#2|, \dots, |#9|) will be an |a/b| fraction
+(without a |[n]| part), where
+the denominator |b| is the product of the denominators of
+|start| and |delta| (for reasons of speed |#1| is not reduced to irreducible
+form, and for another reason explained later |start| and |delta| are not put
+either into irreducible form; the input may use explicitely \csa{xintIrr} to
+achieve that).
+\begin{everbatim*}
+\begingroup\small
+\noindent\parbox{\dimexpr\linewidth-3em}{\color[named]{OrangeRed}%

+ \xintifGt {#1}{1.123}{\xintBreakFor}{, }%
+ }}
+\endgroup\smallskip
+\end{everbatim*}
+
+\smallskip The example above confirms that computations are done exactly, and
+illustrates that the two initial (reduced) denominators are not multiplied when
+they are found to be equal. It is thus recommended to input |start| and |delta|
+with a common smallest possible denominator, or as fixed point numbers with the
+same numbers of digits after the decimal mark; and this is also the reason why
+|start| and |delta| are not by default made irreducible. As internally the
+computations are done with numerators and denominators completely expanded, one
+should be careful not to input numbers in scientific notation with exponents in
+the hundreds, as they will get converted into as many zeroes.
+
+\begin{everbatim*}
+\noindent\parbox{\dimexpr.7\linewidth}{\raggedright

+ {\textcolor{blue}{\tmp}}
+ {\tmp}%
+ \xintifGt {#1}{2}{\xintBreakFor}{, }%
+ }}\smallskip
+\end{everbatim*}
+
+We see here that \csbxint{Trunc} outputs (deliberately) zero as $0$, not (here)
+$0.000$, the idea being not to lose the information that the truncated thing was
+truly zero. Perhaps this behavior should be changed? or made optional? Anyhow
+printing of fixed points numbers should be dealt with via dedicated packages
+such as |numprint| or |siunitx|.\par
+
+
+\subsection{\csbh{xintForpair}, \csbh{xintForthree}, \csbh{xintForfour}}\label{xintForpair}\label{xintForthree}\label{xintForfour}
+
+The syntax\ntype{on} is illustrated in this
+example. The notation is the usual one for |n|-uples, with parentheses and
+commas. Spaces around commas and parentheses are ignored.
+%
+\begin{everbatim*}
+{\centering\begin{tabular}{cccc}
+ \xintForpair #1#2 in { ( A , a ) , ( B , b ) , ( C , c ) } \do {%

+ -#4- & -#2-\\
+ \end{tabular}$\Biggr)$&}\\\noalign{\vskip1\jot}}%
+\end{tabular}\\}
+\end{everbatim*}
+
+\csbxint{Forpair} must be followed by either |#1#2|, |#2#3|, |#3#4|, \dots, or
+|#8#9| with |#1| usable as an alias for |#1#2|, |#2| as alias for |#2#3|,
+etc \dots\ and similarly for \csbxint{Forthree} (using |#1#2#3| or simply
+|#1|, |#2#3#4| or simply |#2|, \dots) and \csbxint{Forfour} (with |#1#2#3#4|
+etc\dots).
+
+Nesting works as long as the macro parameters are distinct among |#1|, |#2|,
+..., |#9|. A macro which expands to an \csa{xintFor} or a
+\csa{xintFor(pair,three,four)} can be used in another one with no constraint
+about using distinct macro parameters.
+
+|\par| tokens are accepted in both the comma separated list and the
+replacement text.
+
+
+\subsection{\csbh{xintAssign}}\label{xintAssign}
+
+\csa{xintAssign}\meta{braced things}\csa{to}%
+\meta{as many cs as they are things} %\ntype{{(f$\to$\lowast [x)}{\lowast N}}
+%
+defines (without checking if something gets overwritten) the control sequences
+on the right of \csa{to} to expand to the successive tokens or braced items
+located to the left of \csa{to}. \csa{xintAssign} is not an expandable macro.
+
+\fexpan sion is first applied to the material in front of \csa{xintAssign}
+which is fetched as one argument if it is braced. Then the expansion of this
+argument is examined and successive items are assigned to the macros following
+|\to|. There must be exactly as many macros as items. No check is done. The
+macro assignments are done with removal of one level of brace pairs from each
+item.
+
+After the initial \fexpan sion, each assigned (brace-stripped) item will be
+expanded according to the setting of the optional parameter.
+
+For example |\xintAssign [e]...| means that all assignments are done using
+|\edef|. With |[f]| the assignments will be made using
+\hyperref[fdef]{\ttfamily\char92fdef}. The default is simply to make the
+definitions with |\def|, corresponding to an empty optional paramter |[]|.
+Possibilities for the optional parameter are: |[], [g], [e], [x], [o], [go],
+[oo], [goo], [f], [gf]|. For example |[oo]| means a double expansion.
+\begin{everbatim*}
+\xintAssign \xintiiDivision{1000000000000}{133333333}\to\Q\R
+\meaning\Q\newline
+\meaning\R\newline
+\xintAssign {{\xintiiDivision{1000000000000}{133333333}}}\to\X
+\meaning\X\newline
+\xintAssign [oo]{{\xintiiDivision{1000000000000}{133333333}}}\to\X
+\meaning\X\newline
+\xintAssign \xintiiPow{7}{13}\to\SevenToThePowerThirteen
+\meaning\SevenToThePowerThirteen\par
+\end{everbatim*}
+
+Two special cases:
+\begin{itemize}[nosep]
+\item if after this initial expansion no brace is found immediately after
+ \csa{xintAssign}, it is assumed that there is only one control sequence
+ following |\to|, and this control sequence is then defined via |\def| (or
+ what is set-up by the optional parameter) to expand to the material between
+ \csa{xintAssign} and \csa{to}.
+\item if the material between \csa{xintAssign} and |\to| is enclosed in two
+ brace pairs, the first brace pair is removed, then the \fexpan sion is
+ immediately stopped by the inner brace pair, hence \csa{xintAssign} now
+ finds a unique item and thus defines only a single macro to be this item,
+ which is now stripped of the second pair of braces.
+\end{itemize}
+
+
+\emph{Note:} prior to release |1.09j|, |\xintAssign| did an |\edef| by default
+for each item assignment but it now does |\def| corresponding to no or empty
+optional parameter.
+
+It is allowed for the successive braced items to be separated by spaces. They
+are removed during the assignments. But if a single macro is defined (which
+happens if the argument after \fexpan sion does not start with a brace),
+naturally the scooped up material has all intervening spaces, as it is
+considered a
+single item. But an upfront initial space will have been absorbed by \fexpan
+sion.
+\begin{everbatim*}
+\def\X{ {a} {b} {c} {d} }\def\Y { u {a} {b} {c} {d} }
+\xintAssign\X\to\A\B\C\D
+\xintAssign\Y\to\Z
+\meaning\A, \meaning\B, \meaning\C, \meaning\D+++\newline
+\meaning\Z+++\par
+\end{everbatim*}
+As usual successive space characters in input make for a single \TeX\ space token.

+
+\csa{xintAssignArray}\meta{braced
+ things}\csa{to}\csa{myArray} %\ntype{{(f$\to$\lowast x)}N}
+%
+first expands fully what comes immediately after |\xintAssignArray| and
+expects to find a list of braced things |{A}{B}...| (or tokens). It then
+defines \csa{myArray} as a macro with one parameter, such that \csa{myArray\x}
+expands to give the |x|th braced thing of this original
+list (the argument \texttt{\x} itself is fed to a |\numexpr| by |\myArray|,
+and |\myArray| expands in two steps to its output). With |0| as parameter,
+\csa{myArray}|{0}| returns the number |M| of elements of the array so that the
+successive elements are \csa{myArray}|{1}|, \dots, \csa{myArray}|{M}|.
+%
+\leftedline{|\xintAssignArray \xintBezout {1000}{113}\to\Bez|} will set
+|\Bez{0}| to \dtt{\Bez0}, |\Bez{1}| to \dtt{\Bez1}, |\Bez{2}| to
+\dtt{\Bez2}, |\Bez{3}| to \dtt{\Bez3}, |\Bez{4}| to
+\dtt{\Bez4}, and |\Bez{5}| to \dtt{\Bez5}:
+\dtt{(\Bez3)${}\times{}$\Bez1${}-{}$(\Bez4)${}\times{}$\Bez2${}={}$\Bez5.}
+This macro is incompatible with expansion-only contexts.
+
+\csa{xintAssignArray} admits an optional parameter, for example
+|\xintAssignArray [e]| means that the definitions of the macros will be made
+with |\edef|. The empty optional parameter (default) means that definitions
+are done with |\def|. Other possibilities: |[], [o], [oo], [f]|. Contrarily to
+\csbxint{Assign} one can not use the |g| here to make the definitions global.
+For this, one should rather do |\xintAssignArray| within a group starting with
+|\globaldefs 1|.
+
+
+\subsection{\csbh{xintDigitsOf}}\label{xintDigitsOf}
+
+This is a synonym for \csbxint{AssignArray},\ntype{fN} to be used to define
+an array giving all the digits of a given (positive, else the minus sign will

+% \lverb!DECIMAL SPLIT
%
+% The macro \xintDecSplit {x}{A} cuts A which is composed of digits (leading
+% zeroes ok, but no sign) (*) into two (each possibly empty) pieces L and R.
+% The concatenation LR always reproduces A.
+%
+% The position of the cut is specified by the first argument x. If x is zero
+% or positive the cut location is x slots to the left of the right end of the
+% number. If x becomes equal to or larger than the length of the number then L
+% becomes empty. If x is negative the location of the cut is |x| slots to the
+% right of the left end of the number.
+%
+% (*) versions earlier than 1.2i first replaced A with its absolute value.
+% This is not the case anymore. This macro should NOT be used for A with a
+% leading sign (+ or -).
+%
+% Entirely rewritten for 1.2i (2016/12/11).
+%
+% Attention: \xintDecSplit not robust against non terminated second argument.
