+`1.3e (2019/04/05)`
+----
+
+### Incompatible changes
+
+ - When defining functions, sub-expressions can only use the
+ `\xint(float)expr...\relax` syntax. One can *not* use there the
+ `\xint(float)eval` wrappers (anyhow they add overhead and can be
+ replaced with the lower level syntax).
+
+### Improvements and new features
+
+ - The **xinttrig** library is automatically loaded by **xintexpr**. It
+ provides direct and inverse trigonometrical functions using either
+ degrees or radians with a precision of up to (a bit less than) 60
+ digits. It is for the most part implemented using high level user
+ interface, but will probably get some optimizations in future (and
+ perhaps extension to more digits).
+ - The **xintlog** library is automatically loaded by **xintexpr**. It
+ uses [poormanlog](http://ctan.org/pkg/poormanlog) to provide
+ logarithms and exponentials with almost 9 digits of precision.
+ Extended precision is for a future release.
+ - **xintexpr**: `\xintdefefunc`, `\xintdeffloatefunc`, `\xintdefiiefunc`
+ define functions which are not protected against expansion in the
+ definition of other functions; refer to `xint.pdf` for the related
+ explanations.
+
+ Notice that whole area of `\xintdef(e)func`, `\xintNewExpr`,
+ `\xintNewFunction` is complex and to be considered still as work in
+ progress as it has a number of shortcomings.
+ - **xintexpr**: `inv()`, `ilog10()`, `sfloat()`, behaviour of
+ `qfloat()` slightly modified.
+ - **xintexpr**: `\xintensuredummy`, `\xintrestorelettervar`.
+ - The optional argument of `\xintfloatexpr` or `\xintfloateval` (it
+ must be at start of braced argument) can be negative; it then means
+ to trim (and round) from the output at float precision that many
+ least significant digits.
+
+### Bug fixes
+
+ - Some bugfixes related to user functions with no variables at all;
+ they were dysfunctional.

+Here are a few important items (bookmark this for reading again later once you
+have gained experience in using this interface...):
+\begin{itemize}
+\item The function names are composed of letters, digits, underscores or |@|
signs. A function name must start with a letter. It may be a single letter
(see \autoref{sssec:overload}).
-
- The variables used in the function signature are single letters (lowercase
- or uppercase) which have \emph{not} been re-declared via \csbxint{defvar} as
- assigned variables. The choice of the letters is entirely up to the user and
- has nil influence on the actual function, naturally.
-
- A function can have at most nine variables.

-
- \csbxint{deffunc} makes the function known only to the \csbxint{expr}
- parser. See \csbxint{defiifunc} and \csbxint{deffloatfunc} for the two other
- parsers.\IMPORTANT

-% \footnotetext{with the current syntax, the |;| as used for |iterr|, |rseq|,
-% |rrseq| must be hidden as |{;}| to not be confused with the |;| ending the
-% declaration.}
-
-
-It is perfectly possible to define functions of variables which stand for
-lists (see \autoref{ssec:lists}), or functions defining lists of comma
-separated items. For example the scalar product and cross product of
-3-dimensional vectors can be defined this way:
+\item The variables used in the function signature are single letters
+ (lowercase or uppercase) which have \emph{not} been re-declared via
+ \csbxint{defvar} as assigned variables. The choice of the letters is
+ entirely up to the user and has nil influence on the actual function,
+ naturally.
+\item A function can have at most nine variables.
+\item The mechanism for functions shares a common code base with the one
+ implementing \csbxint{NewExpr}. This means it shares its features and also
+ its \hyperref[sssec:limitations]{limitations}. %
+
+ Most notably,\IMPORTANT{} the |1.3d| \csbxint{eval}, \csbxint{ieval},
+ \csbxint{floateval} can not be used inside the parsed
+ expression: only the lower level syntax
+ \csbxint{expr}|...\relax| et al. is accepted (and not
+ \csbxint{theexpr} et al.\CHANGED{1.3e} which are about the same as \csbxint{eval} et al.).
+ Prior to |1.3e| \csbxint{NewExpr} and \csbxint{deffunc} diverged on that
+ point, but their behaviour is now identical.
+\item In order to allow recursive constructs, a core mechanism is implemented
+ which inhibits immediate expansion in a new definition; think of
+ \csbxint{deffunc} as being
+ analogous to a |\protected\edef|. This means that another function
+ |bar(x,..)| whose definition uses |foo(17.5)| will only store that it should
+ at some point compute
+ |foo(17.5)|, in place of storing its actual value.
+\item If |foo(x)| definition is not recursive, then you should use
+ \csbxint{defefunc} rather. This is analogous to an |\edef| without the
+ |\protected|.\NewWith{1.3e} Then |bar(x,...)| (defined with
+ \csbxint{deffunc} or \csbxint{defefunc}) will store the actual
+ evaluation of |foo(17.5)|.
+\item If |foo(x)| definition does need recursivity and you want to use
+ efficiently |foo(17.5)| in another function definition, assign it to a
+ variable (see \csbxint{defvar}) and use that variable rather in the
+ definition of |bar()|. Notice that only the variable value, not its name,
+ gets stored, so the variable name is a temporary auxiliary. In the analogy
+ with TeX macros one can think of \csbxint{defvar} or \csbxint{eval} as
+ producing expansion like typesetting does, whereas \csbxint{deffunc} is like
+ a
+ |\protected\edef|, and \csbxint{defefunc} an |\edef| not making the defined
+ function |\protected|.
+\item A function declared via \csbxint{deffunc} remains unknown to
+ \csbxint{floatexpr} (or \csbxint{floateval}). See \csbxint{deffloatfunc},
+ \csbxint{defiifunc}. One can use the same formula in a new definition, but
+ if one wants the expansion to execute in a parser independent way, one can
+ transfer a function like this:\NewWith{1.3e}
\begin{everbatim}
-\xintdeffunc dprod(V, W) := [V][0]*[W][0] + [V][1]*[W][1] + [V][2]*[W][2];
-\xintdeffunc cprod(V, W) := [V][1]*[W][2] - [V][2]*[W][1],
- [V][2]*[W][0] - [V][0]*[W][2],
- [V][0]*[W][1] - [V][1]*[W][0];
-\xintdeffunc Det3(U, V, W) := dprod(cprod(U, V), W);
+\xintdeffloatfunc foo(x) := float(\xintexpr foo(x)\relax);
\end{everbatim}
+ The \func{float} wrapper is in order for the float variant to produce an
+ already-rounded value, possibly speeding-up usage if used as input for other
+ functions. And in the reverse direction one can do:
+\begin{everbatim}
+\xintdeffunc bar(x) := \xintfloatexpr bar(float(x))\relax;
+\end{everbatim}
+ With this the transplanted float-function will expand in \csbxint{expr} as it
+ would have in \csbxint{floatexpr}, i.e. using float operations; this is different
+ from declaring the function again with the same expression as used for the
+ original, as it would have then been parsed with a mapping of infix operators to the
+ macros doing the exact operations, not the floating point ones.
-The mechanism for functions is identical with the one underlying the
-\csbxint{NewExpr} macro (and has the same
-\hyperref[sssec:limitations]{limitations}). See \csbxint{exprSafeCatcodes} for
-catcode matters.
+ The |float(x)| above is not mandatory but recommended. The macro associated
+ to the user float function |bar(x)| may use many times its argument |x| and
+ it does not care to round it, because it basically expect an already rounded
+ value; but in \csbxint{expr} that value could very well be a fraction
+ |19/13| and its float rounding will be done again by each float macro
+ receiving it as argument; with a \func{float} used as above this will have
+ already been done once and the ulterior roundings are faster: they have
+ nothing to do apart from realizing that they have nothing to do.... One can
+ also use \func{sfloat}, this would serve to nothing for the |19/13| case but
+ would possibly for a short integer input involved in multiplications.
+\item If the expression uses an \func{iterr}, \func{rseq}, or \func{rrseq}) it
+ must hide its |;| inside braces to let it not be confused with the ending
+ |;|.
+\item \csbxint{deffunc} tries to set the catcode of |;| before fetching the
+ expression as a delimited parameter, but this is too late if the whole thing
+ was already fetched as argument to some macro. On the other hand the
+ (reasonable) catcode of the |:| does not matter at all, actually this colon
+ before the equality sign is optional.

+\xintdeffunc GCD(a,b):=if(b,GCD(b,a/:b),a);
+\end{everbatim*}
+This of course is the Euclide algorithm: it will be here applied to variables

+\begin{everbatim*}
+\xinttheexpr GCD(385/102, 605/238)\relax
+\end{everbatim*}
+
+But there is already a built-in \func{gcd} (which
+accepts arbitrarily many arguments):
+\begin{everbatim*}
+\xinttheexpr gcd(385/102, 605/238)\relax
+\end{everbatim*}
+
+Since |1.3d| the built-in \func{gcd} accepts inputs being fractions and
+produces the positive generator of the corresponding fractional ideal. And
+loading of \xintgcdname is not needed for this function to be available.\NewWith{1.3d}
+
+Our second example is modular exponentiation:
+\begin{everbatim*}
+\xintdefiifunc powmod_a(x, m, n) :=
+ ifone(m,
+ % m=1, return x modulo n
+ x /: n,
+ % m > 1 test if odd or even and do recursive call

+ sqr(powmod_a(x, m//2, n)) /: n
+ )
+ );
+\xintdefiifunc powmod(x, m, n) := if(m, powmod_a(x, m, n), 1);
+\end{everbatim*}
+I have made the definition here for the |\xintiiexpr| parser; we could do the
+same for the |\xintexpr|-parser (but its usage with big powers would quickly
+create big denominators, think |powmod(1/2, 1000, 1)| for example.)

+\end{everbatim*}
+The function assumes the exponent is non-negative (the Python |pow| behaves
+the same), but zealous users will add the necessary code for negative
+exponents, after having defined another function for modular inverse!
+
+It is mandatory for such definitions to use the \func{if} function, and not
+the |(x)?{A}{B}| construct which much choose a branch. The parsing of the
+\func{if} function keeps the memory of the two alternative branches; to the
+contrary, the \emph{constructed} |powmod| function will expand \emph{only} the
+then relevant branch. This is of course absolutely needed for things such as
+the Euclide algorithm where it would be catastrophic to evaluate both branches
+as the first one involves a division by |b| and the algorithm stops only when
+|b| is actually zero.
+
+If function |A| needs function |B| which needs function |A| start by giving to
+|B| some dummy definition, define |A|, then define |B| properly. TODO: add

+\subsection{\csh{xintreloadxinttrig}}\label{xintreloadxinttrig}
+
+\begin{framed}
+ After modifying \csbxint{Digits},\IMPORTANTf{} one must issue
+ \csbxint{reloadxinttrig} to let the package re-configure itself.
+\end{framed}
+
+The library is pre-configured to be able to handle a precision of up to about
+\fbox{\dtt{60}} digits (make this \dtt{59} at most for the inverse functions).
+But absence of guard digits (whether in the used hard-coded constants or in
+passing over values from one auxiliary function to the next) due to high level
+(user) interface used for the programming means that the produced values are
+definitely expected to be wrong in the last digit or last two digits. I should
+actually give some estimate of the actual maximal error in |ulps| unit, but I
+have not done the complete analysis for lack of time.
+
+Final computation results should thus probably be printed via
+\csbxint{floateval}|{[-2]....}| in order to strip off (with rounding) the last
+two digits, if one does not like seeing those non-meaningful figures in the
+last one or two positions (I don't say those last two figures are
+\emph{systematically} off). For example, to achieve \dtt{16} digits of
+precision one should work with a precision of 18 digits (being careful to have
+issued \csbxint{reloadxinttrig}) and round results using
+\csbxint{floateval}|{[-2]....}|.
+
+Another approach is to use \csbxint{ieval}|{[D]...}| for conversion to
+a fixed point format.
+
+In future, lower level coding will probably replace the high-level interface,
+or at least the macros produced by the high-level interface will be hacked
+into to tell the float macros to work at a somewhat elevated precision.
+
+\subsection{Constants}
+
+They are the correct rounding to \csbxint{Digits} precision of the
+mathematically exact ones. Their values get incorporated into the
+trigonometrical functions at the time of their definitions during loading or
+reloading of the package. They are left free to use, or modified, or
+\csbxint{unassignvar}'d, as this will have no impact whatsoever on the
+functions.

+
+\subsubsection{Conversion functions (optional definitions left to user
+ decision)}
+
+Python provides functions |degrees()| and |radians()|. But as most of the
+\xinttrigname functions are already defined for the two units, I felt this was
+not really needed. It is a oneliner to add them:
+\begin{everbatim}
+\xintdeffloatefunc radians(x) := x * oneDegree;
+\xintdeffloatefunc degrees(x) := x * oneRadian;
+\xintdefefunc radians(x) := x * oneDegree;
+\xintdefefunc degrees(x) := x * oneRadian;
+\end{everbatim}
+
+The variants for \csbxint{expr} above do an exact multiplication, I did not
+add a \func{float} wrapper to force rounding as anyhow the trigonometrical
+functions will do this initial rounding of their arguments. But if you define
+a variable for multiple later use using such a |degrees()| function, it would
+be better to add a \func{float} wrapper in the variable definition so the
+rounding is already done: rounding an already rounded value is unavoidable
+overhead but proceeds faster as it is quicly realized the input actually needs
+no rounding.
+
+Notice however that the conversion factors above are without guard digits. One
+can do this:
+\begin{everbatim}
+\xintdeffloatefunc radians(x) := float(\xintexpr x * oneDegreewithmoredigits\relax);
+\xintdeffloatefunc degrees(x) := float(\xintexpr x * oneRadianwithmoredigits\relax);
+\end{everbatim}
+But recall that |x| will normally already be a rounded value, so this is
+perhaps a bit complex for not much ado. Probably better to work overall with
+an elevated precision and print final results at a lower precision.
+
+\subsection{Important implementation notes}
+\label{ssec:trignotes}
+
+\begin{itemize}
+\item The package is almost entirely implemented using the high level user
+ interface of \xintexprname, see \autoref{sec:xintexprsyntax} for
+ \csbxint{deffloatefunc} and \csbxint{deffloatvar}, the main two exceptions
+ are:
+ \begin{enumerate}[nolistsep]
+ \item the range reduction for the |sind()| and |cosd()| functions which
+ required for optimized efficiency the coding at some more core level.
+ \item a change at core level was done to \csbxint{deffunc} in order to
+ facilitate the transfer of the defined functions from the float parser to
+ the exact parser. See \autoref{sssec:limitations}, the source code
+ comments in |sourcexint.pdf| and the discussion of \csbxint{deffunc} for
+ details. The \csbxint{defefunc} added at |1.3e| was also motivated by this
+ context.
+ \end{enumerate}
+ To avoid problems if the package is reloaded at a time the user has
+ used some letter variables as assigned variables, I added
+ \csbxint{ensuredummy} and \csbxint{restorelettervar}.
+\item It is not possible from this interface to (easily) let the computation
+ proceed with a temporarily elevated precision (``guard digits''). Expect
+ thus some errors in the last places; basically one should use the optional
+ rounding argument of either \csbxint{floateval} or \csbxint{ieval} to reduce
+ the number of digits of printed values by about two digits, if one
+ hopes to get correct rounding (most of the time).
+\item Currently, \xintname is lacking some dedicated internal representation
+ of floats which means that most operations re-parse the digit tokens of their
+ arguments to count them\dots\ this does not contribute to efficiency (you
+ can load the module under |\xintverbosetrue| regime and see how the nested
+ macros look like and get an idea of how many times some rather silly
+ re-counting of mantissa lengths will get done!)
+\item One should not overwrite some function names which are employed as
+ auxiliaries: |sin_aux|, |cos_aux|, |sin_|, |cos_|, |sind_|, |cosd_|,
+ |asin_l|\dots others\dots |asin_a|, |asind_a|, |atan_a|, |atand_a|,
+ |atan_b|, |atand_b|. If you redefine any one of them, you break the
+ whole thing.
+\item Floats with large exponents are integers and are multiple of \dtt{1000};
+ hence modulo \dtt{360} all such ``angles'' are multiple of \dtt{40} degrees.
+ Needless to say that considering usage of the sine and cosine functions
+ with such large float numbers is meaningless.
+\item Regarding such a big float angle in radians, \xinttrigname converts
+ it to degrees by multiplication by (pre-rounded) $180/\pi$, then it does
+ range reduction modulo $360$ and goes back to radians in the appropriate
+ octants and use the series (roughly said). Thus |cos()| and |sin()| will be
+ evaluated as if at some of the finitely many rounded multiples of (exact)
+ $2\pi/9$. When the unit in the last place of the original input was for
+ example \dtt{1e9} it is clear that the final result means nothing at all;
+ this intrinsic problem is not one of conversion from radians to degrees: the
+ unit in the last place interval extends above possibly astronomical numbers of
+ intervals of length $2\pi$. This is an in-built inadequacy of (large)
+ floating point numbers for trigonometrical evaluations; the argument should
+ be treated then as a uniformly distributed random variable modulo $2\pi$,
+ and the sine and cosine values should be random variables realizing the value
+ distribution of these mathematical functions. Clearly this adds some
+ programming complication of deciding how to make the transition. Too lazy
+ for that.
+\item Did I say the implementation was done at very high level (for the most
+ part), hence has ample room for optimization? This is particularly the case
+ for the handling of small inputs by functions such as sine or arcsine.

This is \expandafter|\xintbndlversion| of \expandafter|\xintbndldate|.
-\begin{itemize}
-\item Release |1.3d| of |2019/01/06|:
- \begin{itemize}[nosep]
-\item \csbn{gcd()} and \csbn{lcm()} in \csbxint{expr}|...\relax| now handle
- general arguments, without converting them to integers,
-\item it is not needed anymore to load package \xintgcdnameimp to benefit from
- \csbn{gcd()} and \csbn{lcm()} in the parsers,
-\item \csbxint{unassignvar} slightly refactored,
-\item \csbxint{ifsgnexpr}, \csbxint{ifsgnfloatexpr}, \csbxint{ifsgniiexpr},
-\item \csbxint{unassignexprfunc} and variants for the other parsers,
-\item \csbn{isone()} and \csbn{isint()},
-\item \csbxint{eval}, \csbxint{ieval}, \csbxint{iieval}, and
- \csbxint{floateval} (attention that these macros previously existed with
- different meanings, now available under new names \csbxint{expro},
- \csbxint{iexpro}, \csbxint{iiexpro}, and \csbxint{floatexpro}),
-\item sadly, in \csbxint{iiexpr}|...\relax| division with a zero dividend and
- a one-digit divisor got broken at |1.2p|. Fixed. Thanks to \textsc{Kpym} for
- report. Sorry for long delay in releasing the bugfix, which was done shortly
- after |1.3c| release.
- \end{itemize}
-\item Release |1.3c| of |2018/06/17|:
- \begin{itemize}[nosep]
- \item \csbxint{globaldefstrue} to give global scope to definitions done by
- \csbxint{defvar}, \csbxint{deffunc}, \csbxint{NewExpr}, et al.
- \item \csbn{qraw()} to allow bypassing the normal mode of functioning
- and reduce memory footprint from parsing (very many) comma separated
- numerical items.
- \item the colon in the |:=| part of the syntax for
- \csbxint{defvar} and variants is now optional; and if present it may be
- an active character or have any (reasonable) catcode.
- \item \csbxint{defvar}, \csbxint{deffunc} and their variants try to set the
- catcode of the semi-colon which delimits their arguments; of course this
- will not work if that catcode is already frozen.
- \item \csbxint{exprSafeCatcodes} sets a toggle to allow some nested usage.
- \item \csbxint{UniformDeviate} is better documented and |sourcexint.pdf| is
- better hyperlinked and includes indices for the macros defined by each
- package.
- \item since |1.3| release, \xintfracnameimp (hence \xintexprnameimp) loaded
- \xintgcdnameimp in contradiction to what documentation says. Removed for now.
- \end{itemize}
-\item Release |1.3b| of |2018/05/18|:
- \begin{itemize}[nosep]
- \item \csbxint{UniformDeviate}, \csbn{random()}, \csbn{qrand()},
- \csbn{randrange()},
- \item and their support macros \csbXINT{inRandomFloatSdigits},
- \csbXINT{inRandomFloatSixteen}, \csbxint{RandomDigits},
- \csbxint{iiRandRange}, \csbxint{iiRandRangeAtoB}, also
- \csbxint{XRandomDigits},
- \item functions defined via \csbxint{deffunc} (et al.) to be without
- argument can be used as |foo()|: |foo(nil)| syntax not anymore required.
- \end{itemize}
-\item Release |1.3a| of |2018/03/07|:
- \begin{itemize}[nosep]
- \item removes from \xintcorenameimp, \xintnameimp and \xintfracnameimp the
- whole deprecation mechanism, as there are no more currently any
- deprecated macro,
- \item adds \csbn{ifone()} and \csbn{ifint()} conditionals to the expression parsers,
- \item has a completely redone \csbXINT{_factortens}, in the style of |1.2|
- release (but about 100 digits at least are needed for noticeable speed
- gain),
- \item and last but not least fixes via addition of \csbxint{ExpandArgs} the
- meaning of user defined functions, which in case of recursivity (as made
- possible at |1.3|) were badly inefficient for lack of expansion of their
- arguments.
- \end{itemize}
-\item Release |1.3| of |2018/03/01|:
- \begin{itemize}[nosep]
- \item removed all macros previously deprecated at |1.2o|,
- \item modified addition, subtraction and modulo operations to use a least
- common multiple for the denominator of the result,
- \item added \csbxint{PIrr}, \csbxint{DecToString} and \csbn{preduce()},
- \item and last but not least refactored extensively the
- \csbxint{NewExpr}/\csbxint{deffunc} mechanism. It got both leaner and stronger
- and makes possible recursive function definitions.
- \end{itemize}
+Please refer to |CHANGES.pdf| or |CHANGES.html|.\centeredline{Internet:
+ \url{http://mirrors.ctan.org/macros/generic/xint/CHANGES.html}}
+We keep here only a brief timeline of the most important changes.
-\item Release |1.2q| of |2018/02/06| was a bugfix release with these changes:
- \begin{itemize}[nosep]
- \item fix to an |1.2l| \xintcorenameimp subtraction bug causing a breakage
- under some rare circumstances |:-(|. It was caused by a refactoring
- left-over (extra |!| in |XINT_sub_l_Ida| replacement text), and should
- have been detected by the test suite, but manual testing from early days
- was not yet entirely included in our automated procedure.
- \item new feature: tacit multiplication in front of digits, for example
- |10!20!30!| or |(10+10)10|.
- \end{itemize}
+At |1.3e| the indices which were added at |1.3c| got removed: their inclusion
+caused extra time in the build of |sourcexint.pdf|, larger file size, and the
+macros created using |\csname...\endcsname| were not indexed, of course the
+indexing of functions would have needed systematic extra mark-up. Besides
+their functionality is advantageously made available via the search function
+in PDF viewers. Already the local tables of contents are useful enough most of
+the time when one searches something.
-\item Release |1.2p| of |2017/12/05|
- had some breaking changes:
- \begin{itemize}[nosep]
- \item new output for the \csbxint{Bezout} macro (\xintgcdnameimp),
- \item the \xintexprnameimp operators |/:| (aka |'mod'|) and |//|, and the
- supporting macros from \xintcorenameimp and \xintfracnameimp, are now
- associated with the \emph{floored} division. Formerly it was the
- \emph{truncated} division. This is breaking change for operands of
- opposite signs.
- \end{itemize}
- Improvements and new features:
- \begin{itemize}[nosep]
- \item \xinttoolsnameimp macro \csbxint{ListWithSep} is faster (first update
- since |1.04-2013/04/25|...).
- \item \csbn{divmod()} function added to the \xintexprnameimp parsers,
- \item \csbxint{defvar}, \csbxint{deffloatvar}, \csbxint{defiivar} extended to allow
- multiple simultaneous assignments.
- \end{itemize}
-
-\item Release |1.2o| of |2017/08/29| deprecated those macros from
- \xintcorenameimp and \xintnameimp which filtered their arguments via
- \csbxint{Num}. Currently these macros execute as formerly but raise an error
- message. This deprecation is overruled for most if \xintfracnameimp is
- loaded as it provides their proper definitions. Some however (like
- |\xintiAdd|) remain deprecated even if loading \xintfracnameimp. All these
- deprecated macros are destined to be removed at some future release.
-
- A few macros got renamed (e.g. |\xintNot| became \csbxint{NOT}.) Former names
- emit a deprecation error and will get removed at some future release.
-
-\item Release |1.2n| of |2017/08/06| removed the \xintbinhexnameimp
- dependencies upon \xintcorenameimp; the package now depends upon, and
- loads, only \xintkernelnameimp. The allowed maximal size for the inputs of
- the base conversion macros got increased. The speed got slightly improved.
-
-\item Release |1.2m| of |2017/07/31| rewrote entirely the \xintbinhexnameimp
- module in the style of the techniques from |1.2| \xintcorenameimp. The new
- macros expand faster but their inputs are now limited to a few thousand
- characters (the earlier routines, which dated back to |1.08| could handle
- (slowly) tens of thousands of digits.)
-
-\item Release |1.2l| of |2017/07/26| refactored the subtraction and also
- \csbxint{iiCmp} got a rewrite. It should certainly use |\pdfstrcmp| for
- dramatic speed-up but I do not want to have to worry about multi-engine
- usage.
-
- Some utility routines in \xintcorenameimp manipulating blocks of eight
- digits and still in |O(N^2)| style got rewritten analogously to the
- |1.2i| version of macros such as \csbxint{Inc}. Also \csbxint{iNum} was
- revisited.
-
- The arithmetic macros of \xintcorenameimp and all macros of
- \xintfracnameimp using \csbXINT{_infrac} were made compatible with arguments
- using non-delimited |\the\numexpr| or |\the\mathcode| etc... But
- \csbxint{iiAbs} and \csbxint{iiOpp} were not modified (to avoid some overhead)
- as well as routines such as \csbxint{Inc} which are primarily for internal
- usage.
-
-\item Release |1.2i| of |2016/12/13| rewrote some legacy macros like
- \csbxint{DSR} or \csbxint{DecSplit} in the style of the techniques of |1.2|. But
- this means also that they got limited to about \dtt{22480} digits for
- the former and \dtt{19970} digits for the latter (this is with the input
- stack size at \dtt{5000} and the maximal expansion depth at \dtt{10000}.)
- This is not really an issue from the point of view of calling macros (such
- as \csbxint{Trunc}, \csbxint{Round}), because they usually had since |1.2| their
- own limitation at about \dtt{19950} digits from other code parts (such as
- division.) The macro \csbxint{XTrunc} (which is not f-expandable however) can
- produce tens of thousands of digits and it escapes these limitations. Old
- macros such as \csbxint{Length} are not limited either (incidentally it got a
- lifting in |1.2i|.) The macros from \xinttoolsnameimp (\csbxint{Keep},
- \csbxint{Trim}, \csbxint{NthElt}) also are not limited (but slower.)
-
-\item Release |1.2| of |2015/10/10| entirely rewrote the core
- arithmetic routines located in \xintcorenameimp. The parser of
- \xintexprnameimp got faster and the limitation at |5000| digits per
- number was removed.
-
-\item Extensive changes in release |1.1| of |2014/10/28| were located in
- \xintexprnameimp. Also with that release, packages \xintkernelnameimp and
- \xintcorenameimp were extracted from \xinttoolsnameimp and \xintnameimp,
- and \csbxint{Add} was modified to not multiply denominators blindly.
-

+% \subsection{Locking and unlocking}
+% \lverb|Some renaming and modifications here with release 1.2 to switch from
+% using chains of \romannumeral-`0 in order to gather numbers, possibly
+% hexadecimals, to using a \csname governed expansion. In this way no more
+% limit at 5000 digits, and besides this is a logical move because the
+% \xintexpr parser is already based on \csname...\endcsname storage of numbers
+% as one token.
+%
+% The limitation at 5000 digits didn't worry me too much because it was not
+% very realistic to launch computations with thousands of digits... such
+% computations are still slow with 1.2 but less so now. Chains or
+% \romannumeral are still used for the gathering of function names and other
+% stuff which I have half-forgotten because the parser does many things.
+%
+% In the earlier versions we used the lockscan macro after a chain of
+% \romannumeral-`0 had ended gathering digits; this uses has been replaced by
+% direct processing inside a \csname...\endcsname and the macro is kept only
+% for matters of dummy variables.
+%
+% Currently, the parsing of hexadecimal numbers needs two nested
+% \csname...\endcsname, first to gather the letters (possibly with a hexadecimal
+% fractional part), and in a second stage to apply \xintHexToDec to do the
+% actual conversion. This should be faster than updating on the fly the number
+% (which would be hard for the fraction part...).|

+% The original was done in January 15 and 16, 2019. It provided |asin()| and
+% |acos()| based on a Newton algorithm approach. Then during March 25-31 I
+% revisited the code, adding more inverse trigonometrical functions (with a
+% modified algorithm, quintically convergent), extending the precision range
+% (so that the package reacts to the \csbxint{Digits} value at time of load,
+% or reload), and replaced high level range reduction by some optimized lower
+% level coding.
+%
+% This led me next to improve upon the innards of \csbxint{deffunc} and
+% \csbxint{NewExpr}, and to add to \xintexprnameimp the \csbxint{defefunc}
+% macro (see user documentation).
+%
+% Finally on April 5, 2019 I pushed the idea of the algorithm for the arcsine
+% function to its logical limit obtaining the method finally in use here.
+%
+% Almost all of the code remains written at high level, and in particular it
+% is not easily feasible from this interface to execute computations with
+% guard digits. Expect the last one or two digits to be systematically off.
+%
+% Also, small floating-point inputs are handled quite sub-optimally both for
+% the direct and inverse functions; substantial gains are possible. I added
+% the ilog10() function too late to consider using it here with the high level
+% interface.

+% Pre-compute 1/n! for n = 2, ..., 44
+%
+% The following example (among many, see below) shows that we must be careful
+% when pre-computing the 1/i!.
+%( Consider 35!=10333147966386144929666651337523200000000.

+%: 9.6775929586318909920898167e-41 which differs by 3ulps from the correct rounding
+%: of 1/35! to 26 places which is 9.6775929586318909920898164e-41. The problem
+%: isn't in the factorial computations, but in the fact that the rounding of the
+%: inverse of a quantity which is itself a rounding is not necessarily the rounding
+%: of the exact inverse of the original.
+%)
+% Here is a little program to explore this phenomenon systematically:
+%
+%( \xintDigits:=55;$%
+%: \edef\tempNlist{\xintSeq{2}{39}}%
+%: \xintFor*#1in{\tempNlist}\do{$% we precompute some rounding here to

+%: \xintfloateval{0+\csname invfact#2\endcsname}}$%

+%: }$%
+%: }$%
+%)
+%
+% We can see that for D=16, the problem is there with N=22, 25, 26, 27,
+% 28...and more. If we were to use 1/i! directly in the \xintdeffloatefunc of
+% sin_aux(X) and cos_aux(X) we would have this problem.
+%
+% If we use \xintexpr1/i!\relax encapsulation in the function declaration the
+% rounding will be delayed to actual use of the function... which is bad, so
+% we need it to happen now. We could use (0+\xintexpr1/i!\relax) inside the

+% result but for readability we use some temporary variables. We could use
+% seq(0+\xintexpr1/i!\relax, i = 2..44) but opt for an rseq. The semi-colon
+% must be braced to hide it from \xintdeffloatvar grabbing of the delimited

+% in the floating point sense causing catastrophic loss of digits when one is
+% near -π. On the other hand my sin(x) function will first convert to degrees
+% then add 180 without any loss of floating point precision, even for a result
+% near zero, then convert back to radians and use the sine series.

+% Compute asin(x)
+%
+% The approach I shall first describe (which is only a first step towards our
+% final approach) converges quintically but requires an initial square root
+% computation. However, when used for atan(x), we then do not have to do any
+% such square root extraction. See code next.
+%
+% The algorithm (for this first approach): we have 0 <= t < 0.72,
+% let t1 = t*(1+t^2/6). We also have
+% u = sqrt(1 - t^2). We seek a = Arcsin t with t = sin(a).
+%
+% Then t1 < Arcsin t and the difference (we don't know it!) δ_1 is < 0.02.
+% We compute D = t*cos(t1)-u*sin(t1). This computation is done "exactly" via
+% the \xintexpr encapsulation. In other terms we use doubled precision.
+% Anyhow, currently (1.3e) the Float macros of xintfrac.sty for multiplication
+% do go via such exact multiplication when the mantissas have the expected
+% sizes. So we can't gain but only lose due to catastrophic subtraction in
+% using float operations here.
+%
+% Thus D is sin(a-t1) = sin(δ_1). And δ_1 = Arcsin D, but D is small!
+% We then use again two terms of the Arcsin series and define
+% t2 = t1 + D * (1 + D^2/6). Let δ_2 = a - t2. Then δ_2 is of the order of
+% the neglected term 3*(δ_1)^5/40.
+%
+% ©copyright J.F. Burnol, March 30, 2019. This surely has a name.
+%
+% The algorithm is quintically convergent! I must have thought about this some
+% many years ago, but I like it a lot and I found it again on March 30, 2019.
+% One can do the same to go from exp to log. Basically the idea is that we can
+% improve the Newton Method for any function f for which knowing target value
+% of f implies one also knows target value of its derivative. In fact I
+% obtained the quintic algorithm by combining the Newton formula with the one
+% from using f(x)/f'(a) and not f(x)/f'(x) in the update to cancel the two
+% quadratic errors.
+%
+% One iteration (t2) gives about 9 digits, two iterations (t3) 49 digits !
+% And if we want hepta-convergence we only need to use one more term
+% of the Arcsin series in the update of the t_n... really this is very nice.
+%
+% And actually (t2) already gives 30 digits of floating point precision for
+% input t<0.1. Let's confirm this:

+% Each iteration costs a computation of one cos and one sine done at the full
+% final precision. This is stupid because we should compute at an evolving
+% precision, but anyhow this is not our problem anymore as our final algorithm
+% is not a loop but it does exactly one iteration for all inputs. As
+% examplified above it remains true that we could improve its speed for small
+% inputs by using shorter auxiliary series (see below).
+%
+% In January I used a loop via an iter() construct, with some subs() to avoid
+% repeating computations. This can only be done in an \xintNewFunction. Here
+% is how it looked after some optimization for the stopping criteria, after
+% replacing generic Newton algorithm by a specific quintic one for arcsine:

+%
+% I don't have time to explain the final algorithm below and how the

+% TeX hackers note 1:
+%
+% The subs( , x = ..) mechanism has no utility in a function definition,
+% there is no parallel mechanism at the underlying macros, so in fact
+% the substituted things will remain unevaluated if they involve
+% indeterminates, so this is exactly like not trying to make things
+% more efficient at all.
+%
+% Currently, the only way is thus to employ auxiliary functions like is done
+% next. Contrarily to TeX macros, we must define the functions one after the
+% other in the correct order, so the auxiliaries come first.
+%
+% TeX hackers note 2:
+%
+% The if(,,) and ifsgn(,,,) tests when used numerically compute all ; but when
+% used into a \xintdeffloatefunc, they are converted to macros with basically
+% \firstofthree, \secondofthree, \thirdofthree behaviour so then only the
+% actually executed branch will do computations.
+%
+% For numeric computations the ? and ?? operators are used for this effect,
+% but they can not be used in \xintdeffloatefunc if the test involves unknown
+% variables; as explained above fortunately then if(,,) and ifsgn(,,) work.
