varying typographic conventions with the same input syntax. The
package includes automated processing of numbers and units, and
the ability to control tabular alignment of numbers.
+
+Installation
+------------
+
+The package is supplied in `dtx` format and as a pre-extracted
+zip file, `siunitx.tds.zip`. The later is most convenient for
+most users: simply unzip this in your local texmf directory . If
+you want to unpack the `.dtx` yourself, running `tex
+siunitx.dtx` will extract the package whereas `latex
+siunitx.dtx` will extract it and also typeset the documentation.
+
+The package requires LaTeX3 support as provided in the
+`l3kernel` and `l3packages` bundles. Both of these are available
+on [CTAN](http://www.ctan.org/) as ready-to-install zip files.
+Suitable versions are available in MiKTeX 2.9 and TeX Live 2015
+(updating the relevant packages online may be necessary).
+LaTeX3, and so `siunitx`, requires the e-TeX extensions: these
+are available on all modern TeX systems.
+
+Typesetting the documentation requires a number of packages in
+addition to those needed to use the package. This is mainly
+because of the number of demonstration items included in the
+text. To compile the documentation without error, you will
+need the packages:
+ - `amsmath`
+ - `booktabs`
+ - `cancel`
+ - `caption`
+ - `cleveref`
+ - `colortbl`
+ - `csquotes`
+ - `datatool`
+ - `helvet`
+ - `mathpazo`
+ - `multirow`
+ - `listings`
+ - `pgfplots`
+ - `xcolor`

-% \subsection{Parsing numbers}
-%
-% Before numbers can be manipulated or formatted they need to be parsed into
-% an internal form. In particular, if multiple code paths are to be avoided,
-% it is necessary to do such parsing even for relatively simple cases such
-% as converting |1e10| to |1 \times 10^{10}|.
-%
-% Storing the result of such parsing can be done in a number of ways. In the
-% first version of \pkg{siunitx} a series of separate data stores were used.
-% This is potentially quite fast (as recovery of items relies only on \TeX{}'s
-% hash table) but makes managing the various data entries somewhat tedious and
-% error-prone. For version two of the package, a single data structure
-% (property list) was used for each part of the parsed number. Whilst this is
-% easy to manage and extend, it is somewhat slower as at a \TeX{} level there
-% are repeated pack--unpack steps. In particular, the fact that there are a
-% limited number of items to track for a \enquote{number} means that a more
-% efficient approach is desirable (contrast parsing units, which is open-ended
-% and therefore fits well with using a property list).
-%
-% To allow for complex numbers, two parallel data structures are used, one for
-% the real part and one for the imaginary part. If the part is entirely absent
-% then the data structures are left empty. Within each part, the structure
-% is
-% \begin{quote}
-% \marg{comparator}\meta{sign}\marg{integer}\marg{decimal}
-% \marg{uncertainty}\\
-% \meta{exponent sign}\marg{exponent}
-% \end{quote}
-% where the two sign parts must be single tokens and all other components
-% must be given in braces. \emph{All} of the components must be present in
-% a stored number (\emph{i.e.}~at the end of parsing). The number must have
-% at least one digit for both the \meta{integer} and \meta{exponent} parts.

-% \begin{documentation}
-%
-% This submodule is focussed on providing controlled printing for numbers and
-% units. Key to this is control of font: conventions for printing quantities
-% mean that the exact nature of the output is important. At the same time, this
-% module provides flexibility for the user in terms of which aspects of the font
-% are responsive to the surrounding general text. Printing material may also
-% take place in text or math mode.
-%
-% The printing routines assume that normal \LaTeXe{} font selection commands
-% are available, in particular \cs{bfsries}, \cs{mathrm}, \cs{mathversion},
-% \cs{mdseries}, \cs{rmfamily} and \cs{upshape}. It also requires the standard
-% \LaTeXe{} kernel commands \cs{ensuremath}, \cs{textsubscript} and
-% \cs{textsuperscript} for printing in text mode. The following packages are
-% also required to provide the functionality detailed.
-% \begin{itemize}
-% \item \pkg{color}: support for color using \cs{textcolor}
-% \item \pkg{textcomp}: \cs{textminus} and \cs{textpm} for printing
-% in text mode
-% \item \pkg{amstext}: the \cs{text} command for printing in text mode
-% \end{itemize}
-%
-% \begin{function}{\siunitx_print:nn, \siunitx_print:nV}
-% \begin{syntax}
-% \cs{siunitx_print:nn} \Arg{type} \Arg{material}
-% \end{syntax}
-% Prints the \meta{material} according the the prevailing settings for the
-% submodule as applicable to the \meta{type} of content: the latter should be
-% either |number| or |unit|. The \meta{material} should comprise normal
-% \LaTeX{} mark-up for numbers or units. In particular, units will typically
-% use |\mathrm| to indicate material to be printed in the current upright
-% roman font, and |^| and |_| will typically be used to indicate super- and
-% subscripts, respectively. These elements will be correctly handled when
-% printing for example using |\mathsf| in math mode, or using only text
-% fonts.
-% \end{function}
-%
-% \begin{variable}{\l_siunitx_print_series_prop}
-% This properly list contains mappings from text mode font weights to math
-% mode font versions. The standard settings here cover
-% \begin{itemize}
-% \item[\texttt{m}] Standard (mid) weight, mapping to math version
-% |normal|.
-% \item[\texttt{bx}] Bold exanded weight, mapping to math version |bold|.
-% \item[\texttt{lt}] Light weight, mapping to math version |light|.
-% \item[\texttt{l}] Light weight, mapping to math version |light|.
-% \end{itemize}
-% \end{variable}
-%
-% \subsection{Key--value options}
-%
-% The options defined by this submodule are available within the \pkg{l3keys}
-% |siunitx| tree.
-%
-% \begin{function}{color}
-% \begin{syntax}
-% |color| = \meta{color}
-% \end{syntax}
-% Color to apply to printed output: the latter should be a named color
-% defined for use with \cs{textcolor}. The standard setting is empty (no
-% color).
-% \end{function}
-%
-% \begin{function}{mode}
-% \begin{syntax}
-% |mode| = \meta{choice}
-% \end{syntax}
-% Selects which mode (math or text) the output is printed in: a choice
-% from the options |match|, |math| or |text|. The option |match| matches
-% the mode prevailing at the point \cs{siunitx_print:nn} is called. The
-% |math| and |text| options choose the relevant \TeX{} mode for printing.
-% The standard setting is |math|.
-% \end{function}
-%
-% \begin{function}{number-color}
-% \begin{syntax}
-% |number-color| = \meta{color}
-% \end{syntax}
-% Color to apply to numbers in output: the latter should be a named color
-% defined for use with \cs{textcolor}. The standard setting is empty (no
-% color).
-% \end{function}
-%
-% \begin{function}{number-mode}
-% \begin{syntax}
-% |number-mode| = \meta{choice}
-% \end{syntax}
-% Selects which mode (math or text) the numbers are printed in: a choice
-% from the options |match|, |math| or |text|. The option |match| matches
-% the mode prevailing at the point \cs{siunitx_print:nn} is called. The
-% |math| and |text| options choose the relevant \TeX{} mode for printing.
-% The standard setting is |math|.
-% \end{function}
-%
-% \begin{function}{propagate-math-font}
-% \begin{syntax}
-% |propagate-math-font| = |true|\verb"|"|false|
-% \end{syntax}
-% Switch to determine if the currently-active math font is applied within
-% printed output. This is relevant only when \cs{siunitx_print:nn} is
-% called from within math mode: in text mode there is not active math
-% font. When not active, math mode material will be typeset using
-% standard math mode fonts without any changes being made to the
-% supplied argument. The standard setting is |false|.
-% \end{function}
-%
-% \begin{function}{reset-math-version}
-% \begin{syntax}
-% |reset-math-version| = |true|\verb"|"|false|
-% \end{syntax}
-% Switch to determine whether the active \cs{mathversion} is reset to
-% |normal| when printing in math mode. Note that math version is typically
-% used to select \cs{boldmath}, though it is also be used by
-% \foreign{e.g.}~\pkg{sansmath}. The standard setting is |true|.
-% \end{function}
-%
-% \begin{function}{reset-text-family}
-% \begin{syntax}
-% |reset-text-family| = |true|\verb"|"|false|
-% \end{syntax}

-% \begin{syntax}
-% |reset-text-series| = |true|\verb"|"|false|
-% \end{syntax}
-% Switch to determine whether the active math series is reset to
-% \cs{mdseries} when printing in text mode. The standard setting is |true|.
-% \end{function}
-%
-% \begin{function}{reset-text-shape}
-% \begin{syntax}
-% |reset-text-shape| = |true|\verb"|"|false|
-% \end{syntax}
-% Switch to determine whether the active math shape is reset to
-% \cs{upshape} when printing in text mode. The standard setting is |true|.
-% \end{function}
-%
-% \begin{function}{text-family-to-math}
-% \begin{syntax}
-% |text-family-to-math| = |true|\verb"|"|false|
-% \end{syntax}
-% Switch to determine if the family of the current text font should be
-% applied (where possible) to printing in math mode. The standard setting is
-% |false|.
-% \end{function}
-%
-% \begin{function}{text-weight-to-math}
-% \begin{syntax}
-% |text-weight-to-math| = |true|\verb"|"|false|
-% \end{syntax}
-% Switch to determine if the weight of the current text font should be
-% applied (where possible) to printing in math mode. This is achieved by
-% setting the \cs{mathversion}, and so will override |reset-math-version|.
-% The mappings between text and math weight are stored in
-% \cs{l_siunitx_print_series_prop}. The standard setting is |false|.
-% \end{function}
-%
-% \begin{function}{unit-color}
-% \begin{syntax}
-% |unit-color| = \meta{color}
-% \end{syntax}
-% Color to apply to units in output: the latter should be a named color

-% \end{function}
-%
-% \begin{function}{unit-mode}
-% \begin{syntax}
-% |unit-mode| = \meta{choice}
-% \end{syntax}
-% Selects which mode (math or text) units are printed in: a choice

-% Collecting a tabular cell means doing a token-by-token collection.
-% In previous versions of \pkg{siunitx} that was done along with picking
-% out the numerical part, but the code flow ends up very tricky. Here,
-% therefore, we just collect up the unchanged tokens first. Some issues
-% with the way that the \texttt{peek} functions are currently set up in
-% \pkg{expl3} mean that at present there is a need to do stuff by hand
-% here. The definition of \cs{cr} is used to allow collection of any tokens
-% inserted after the main content when dealing with the last cell of a row:
-% the \enquote{group} around it is needed to avoid issues with the underlying
-% |\halign|. (The approach is based on that in \pkg{collcell}.) Notice that
-% as each cell forms a group there is no need to reset the definition of
-% \cs{cr}.

-% \subsection{Printing numbers in cells: spacing}
-%
-% Getting the general alignment correct in tables is made more complex than one
-% would like by the \pkg{colortbl} package. In the original \LaTeXe{}
-% definition, cell material is centred by a construction of the (primitive)
-% form
-% \begin{verbatim}

-% \hskip 0pt plus 0.5fill
-% \kern 0pt
-% #
-% \hskip 0pt plus 0.5fill

-% \begin{documentation}
-%
-% This submodule is dedicated to formatting physical units. The main function,
-% \cs{siunitx_unit_format:nN}, takes user input specify physical units and
-% converts it into a formatted token list suitable for typesetting in math
-% mode. While the formatter will deal correctly with \enquote{literal} user
-% input, the key strength of the module is providing a method to describe
-% physical units in a \enquote{symbolic} manner. The output format of these
-% symbolic units can then be controlled by a number of key--value options
-% made available by the module.
-%
-% A small number of \LaTeXe{} math mode commands are assumed to be available
-% as part of the formatted output. The \cs{mathchoice} command
-% (normally the \TeX{} primitive) is needed when using
-% |per-mode = symbol-or-fraction|. The command \cs{mathrm} is used for
-% wrapping the text (letter) part of units. The commands \cs{frac},
-% \cs{mbox}, \verb*|\ | and \cs{,} are used by the standard module settings,
-% and \cs{ensuremath}, \cs{hbar}, \cs{mathit} and \cs{mathrm} in some standard
-% unit definitions (for atomic and natural units). For the display of colored
-% (highlighted) and cancelled units, the commands \cs{textcolor} and
-% \cs{cancel} are assumed to be available.
-%
-% \section{Formatting units}
-%
-% \begin{function}{\siunitx_unit_format:nN}
-% \begin{syntax}
-% \cs{siunitx_unit_format:nN} \Arg{units} \meta{tl~var}
-% \end{syntax}
-% This function converts the input \meta{units} into a processed
-% \meta{tl~var} which can then be inserted in math mode to typeset the
-% material. Where the \meta{units} are given in symbolic form, described
-% elsewhere, this formatting process takes place in two stages: the
-% \meta{units} are parsed into a structured form before the generation
-% of the appropriate output form based on the active settings. When the
-% \meta{units} are given as literals, processing is minimal: the
-% characters |.| and |~| are converted to unit products (boundaries).
-% In both cases, the result is a series of tokens intended to be typeset
-% in math mode with appropriate choice of font for typesetting of the
-% textual parts.
-%
-% For example,
-% \begin{verbatim}
-% \siunitx_unit_format:nN { \kilo \metre \per \second } \l_tmpa_tl
-% \end{verbatim}
-% will, with standard settings, result in \cs{l_tmpa_tl} being set to
-% \begin{verbatim}
-% \mathrm{km}\,\mathrm{s}^{-1}
-% \end{verbatim}
-% \end{function}
-%
-% \begin{function}{\siunitx_unit_format:nNN}
-% \begin{syntax}
-% \cs{siunitx_unit_format:nNN} \Arg{units} \meta{tl~var} \meta{fp~var}
-% \end{syntax}
-% This function formats the \meta{units} in the same way as described for
-% \cs{siunitx_unit_format:nN}. When the input is given in symbolic form,
-% any decimal unit prefixes will be extracted and the overall power of
-% ten that these represent will be stored in the \meta{fp~var}.
-%
-% For example,
-% \begin{verbatim}
-% \siunitx_unit_format:nNN { \kilo \metre \per \second }
-% \l_tmpa_tl \l_tmpa_fp
-% \end{verbatim}
-% will, with standard settings, result in \cs{l_tmpa_tl} being set to
-% \begin{verbatim}
-% \mathrm{m}\,\mathrm{s}^{-1}
-% \end{verbatim}
-% with \cs{l_tmpa_fp} taking value~$3$. Note that the latter is a floating
-% point variable: it is possible for non-integer values to be obtained here.
-% \end{function}
-%
-% \section{Defining symbolic units}
-%
-% \begin{function}{\siunitx_declare_prefix:Nnn}
-% \begin{syntax}
-% \cs{siunitx_declare_prefix:Nnn} \meta{prefix} \Arg{symbol} \Arg{power}
-% \end{syntax}
-% Defines a symbolic \meta{prefix} (which should be a control sequence
-% such as |\kilo|) to be converted by the parser to the \meta{symbol}.
-% The latter should consist of literal content (\emph{e.g.}~|k|).
-% In literal mode the \meta{symbol} will be typeset directly. The prefix
-% should represent an integer \meta{power} of $10$, and this information
-% may be used to convert from one or more \meta{prefix} symbols to an
-% overall power applying to a unit. See also
-% \cs{siunitx_declare_prefix:Nn}.
-% \end{function}
-%
-% \begin{function}{\siunitx_declare_prefix:Nn}
-% \begin{syntax}
-% \cs{siunitx_declare_prefix:Nn} \meta{prefix} \Arg{symbol}
-% \end{syntax}
-% Defines a symbolic \meta{prefix} (which should be a control sequence
-% such as |\kilo|) to be converted by the parser to the \meta{symbol}.
-% The latter should consist of literal content (\emph{e.g.}~|k|).
-% In literal mode the \meta{symbol} will be typeset directly. In contrast
-% to \cs{siunitx_declare_prefix:Nnn}, there is no assumption about the
-% mathematical nature of the \meta{prefix}, \emph{i.e.}~the prefix may
-% represent a power of any base. As a result, no conversion of the
-% \meta{prefix} to a numerical power will be possible.
-% \end{function}
-%
-% \begin{function}{\siunitx_declare_power:NNn}
-% \begin{syntax}
-% \cs{siunitx_declare_power:NnN} \meta{pre-power} \meta{post-power} \Arg{value}
-% \end{syntax}
-% Defines \emph{two} symbolic \meta{powers} (which should be control
-% sequences such as |\squared|) to be converted by the parser to the
-% \meta{value}. The latter should be an integer or floating point number in
-% the format defined for \pkg{l3fp}. Powers may precede a unit or be give
-% after it: both forms are declared at once, as indicated by the argument
-% naming. In literal mode, the \meta{value} will be applied as
-% a superscript to either the next token in the input (for the
-% \meta{pre-power}) or appended to the previously-typeset material
-% (for the \meta{post-power}).
-% \end{function}
-%
-% \begin{function}{\siunitx_declare_qualifier:Nn}
-% \begin{syntax}
-% \cs{siunitx_declare_qualifier:Nn} \meta{qualifier} \Arg{meaning}
-% \end{syntax}
-% Defines a symbolic \meta{qualifier} (which should be a control sequence
-% such as |\catalyst|) to be converted by the parser to the \meta{meaning}.
-% The latter should consist of literal content (\emph{e.g.}~|cat|). In
-% literal mode the \meta{meaning} will be typeset following a space after
-% the unit to which it applies.
-% \end{function}
-%
-% \begin{function}{\siunitx_declare_unit:Nn, \siunitx_declare_unit:Nx}
-% \begin{syntax}
-% \cs{siunitx_declare_unit:Nn} \meta{unit} \Arg{meaning}
-% \end{syntax}
-% Defines a symbolic \meta{unit} (which should be a control sequence
-% such as |\kilogram|) to be converted by the parser to the \meta{meaning}.
-% The latter may consist of literal content (\emph{e.g.}~|kg|), other
-% symbolic unit commands (\emph{e.g.}~|\kilo\gram|) or a mixture of the two.
-% In literal mode the \meta{meaning} will be typeset directly.
-% \end{function}
-%
-% \begin{variable}{\l_siunitx_unit_symbolic_seq}
-% This sequence contains all of the symbolic \meta{unit} names defined :
-% these will be in the form of control sequences such as |\kilogram|.
-% The order of the sequence is unimportant.
-% \end{variable}
-%
-% \section{Pre-defined symbolic unit components}
-%
-% The unit parser is defined to recognise a number of pre-defined units,
-% prefixes and powers, and also interpret a small selection of
-% \enquote{generic} symbolic parts.
-%
-% Broadly, the pre-defined units are those defined by the \textsc{bipm} in the
-% documentation for the \emph{International System of Units} (SI)~\cite{BIPM}.
-% As far as possible, the names given to the command names for units are those
-% used by the \textsc{bipm}, omitting spaces and using only \textsc{ascii}
-% characters. The standard symbols are also taken from the same documentation.
-% In the following documentation, the order of the description of units
-% broadly follows the SI~Brochure.
-%
-% \begin{function}
-% {
-% \kilogram ,
-% \metre ,
-% \meter ,
-% \mole ,
-% \kelvin ,
-% \candela ,
-% \second ,
-% \ampere
-% }
-% The base units as defined in Section~2.1 of the SI Brochure~\cite{SI:2.1}.
-% Notice that \cs{meter} is defined as an alias for \cs{metre} as the former
-% spelling is common in the US (although the latter is the official spelling).
-% \end{function}
-%
-% \begin{function}{\gram}
-% The base unit \cs{kilogram} is defined using an SI prefix: as such the
-% (derived) unit \cs{gram} is required by the module to correctly produce
-% output for the \cs{kilogram}.
-% \end{function}
-%
-% \begin{function}
-% {
-% \yocto ,
-% \zepto ,
-% \atto ,
-% \femto ,
-% \pico ,
-% \nano ,
-% \micro ,
-% \milli ,
-% \centi ,
-% \deci ,
-% \deca ,
-% \deka ,
-% \hecto ,
-% \kilo ,
-% \mega ,
-% \giga ,
-% \tera ,
-% \peta ,
-% \exa ,
-% \zetta ,
-% \yotta
-% }
-% Prefixes, all of which are integer powers of $10$: the powers are stored
-% internally by the module and can be used for conversion from prefixes to
-% their numerical equivalent. These prefixes are documented in Section~3.1
-% of the SI~Brochure~\cite{SI:3.1}.
-%
-% Note that the \cs{kilo} prefix is required to
-% define the base \cs{kilogram} unit. Also note the two spellings available
-% for \cs{deca}/\cs{deka}.
-% \end{function}
-%
-% \begin{function}
-% {
-% \becquerel ,
-% \degreeCelsius ,
-% \coulomb ,
-% \farad ,
-% \gray ,
-% \hertz ,
-% \henry ,
-% \joule ,
-% \katal ,
-% \lumen ,
-% \lux ,

-% \radian ,
-% \siemens ,
-% \sievert ,
-% \steradian ,
-% \tesla ,
-% \volt ,
-% \watt ,
-% \weber
-% }
-% The defined SI~units with defined names and symbols, as given in
-% Section~2.2.2 of the SI~Brochure~\cite{SI:2.2.2}. Notice that the names
-% of the units are lower case with the exception of \cs{degreeCelsius}, and
-% that this unit name includes \enquote{degree}.
-% \end{function}
-%
-% \begin{function}
-% {
-% \day ,
-% \hectare ,
-% \hour ,
-% \litre ,
-% \liter ,
-% \minute ,
-% \tonne
-% }
-% Units accepted for use with the SI: here \cs{minute} is a unit of time
-% not of plane angle. These units are taken from Table~4.1 of the
-% SI~Brochure~\cite{SI:T6}.
-%
-% For the unit \cs{litre}, both |l| and |L| are listed
-% as acceptable symbols: the latter is the standard setting of the module.
-% The alternative spelling \cs{liter} is also given for this unit for US
-% users (as with \cs{metre}, the official spelling is \enquote{re}).
-% \end{function}
-%
-% \begin{function}
-% {
-% \arcminute ,
-% \arcsecond ,
-% \degree
-% }
-% Units for plane angles accepted for use with the SI: to avoid a clash
-% with units for time, here \cs{arcminute} and \cs{arcsecond} are used in
-% place of \cs{minute} and \cs{second}. These units are taken from Table~4.1
-% of the SI~Brochure~\cite{SI:T6}.

-% \begin{macro}{\@@_if_symbolic:nTF}
-% The test for symbolic units is needed in two places. First, there is the

-% when parsing there is a need to check if the current unit is built up

-% and to do nothing, with the few special cases handled manually. If
-% an \texttt{f}-type definition then yields nothing at all then the
-% assumption is that the input is symbolic. (We use \texttt{f}-type
-% expansion since it will turn the symbolic unit names into nothing at
-% all but doesn't require them to be expandable.)

-% \subsection{Defining symbolic unit}
-%
-% Unit macros and related support are created here. These exist only within
-% the scope of the unit processor code, thus not polluting document-level
-% namespace and allowing overlap with other areas in the case of useful short
-% names (for example \cs{pm}). Setting up the mechanisms to allow this requires
-% a few additional steps on top of simply saving the data given by the user
-% in creating the unit.
-%
-% \begin{variable}{\l_siunitx_unit_symbolic_seq}
-% A list of all of the symbolic units, \emph{etc.}, set up. This is needed
-% to allow the symbolic names to be defined within the scope of the unit
-% parser but not elsewhere using simple mappings.
-% \begin{macrocode}
-\seq_new:N \l_siunitx_unit_symbolic_seq

-%
-% \begin{macro}{\@@_set_symbolic:Nnn}
-% \begin{macro}{\@@_set_symbolic:Npnn}
-% \begin{macro}{\@@_set_symbolic:NNpnn}
-% The majority of the work for saving each symbolic definition is the same
-% irrespective of the item being defined (unit, prefix, power, qualifier).
-% This is therefore all carried out in a single internal function which
-% does the common tasks. The three arguments here are the symbolic macro
-% name, the literal output and the code to insert when doing full unit
-% parsing. To allow for the \enquote{special cases} (where arguments are
-% required) the entire mechanism is set up in a two-part fashion allowing
-% for flexibility at the slight cost of additional functions.
-%
-% Importantly, notice that the unit macros are declared as expandable. This
-% is required so that literals can be correctly converted into a token list
-% of material which does not depend on local redefinitions for the unit
-% macros. That is required so that the unit formatting system can be grouped.

-% benefits.
-%
-% \begin{macro}{\per}

-% \subsection{Main formatting routine}
-%
-% Unit input can take two forms, \enquote{literal} units (material to be
-% typeset directly) or \enquote{symbolic} units (macro-based). Before any
-% parsing or typesetting is carried out, a small amount of pre-parsing has to

-%
-% \begin{variable}{\l_@@_product_tl}

- }
-% \end{macrocode}
-% \end{variable}
-%
-% \begin{variable}{\l_@@_formatted_tl}
-% A token list for the final formatted result: may or may not be generated
-% by the parser, depending on the nature of the input.
-% \begin{macrocode}
-\tl_new:N \l_@@_formatted_tl
-% \end{macrocode}
-% \end{variable}
-%
-% \begin{macro}{\siunitx_unit_format:nN}
-% \begin{macro}{\siunitx_unit_format:nNN}
-% \begin{macro}{\@@_format:nNN}
-% \begin{macro}{\@@_format_aux:}
-% Formatting parsed units can take place either with the prefixes printed or
-% separated out into a power of ten. This variation is handled using two
-% separate functions: as this submodule does not really deal with numbers,
-% formatting the numeral part here would be tricky and it is better therefore
-% to have a mechanism to return a simple numerical power. At the same time,
-% most uses will no want this more complex return format and so a version of
-% the code which does not do this is also provided.
-%
-% The main unit formatting routine groups all of the parsing/formatting, so
-% that the only value altered will be the return token list. As definitions
-% for the various unit macros are not globally created, the first step is to
-% map over the list of names and active the unit definitions: these do
-% different things depending on the switches set. There is then a decision to
-% be made: is the unit input one that can be parsed (\enquote{symbolic}), or
-% is is one containing one or more literals. In the latter case, there is a
-% still the need to convert the input into an expanded token list as some
-% parts of the input could still be using unit macros.
-%
-% Notice that for \cs{siunitx_unit_format:nN} a second return value from the
-% auxiliary has to be allowed for, but is simply discarded.

-% \subsection{Parsing symbolic units}
-%
-% Parsing units takes place by storing information about each unit in a
-% \texttt{prop}. As well as the unit itself, there are various other optional
-% data points, for example a prefix or a power. Some of these can come before
-% the unit, others only after. The parser therefore tracks the number of units
-% read and uses the current position to allocate data to individual units.
-%
-% The result of parsing is a property list (\cs{l_@@_parsed_prop}) which
-% contains one or more entries for each unit:
-% \begin{itemize}
-% \item \texttt{prefix-$n$} The symbol for the prefix which applies to this
-% unit, \emph{e.g.} for \cs{kilo} with (almost certainly) would be
-% |k|.
-% \item \texttt{unit-$n$} The symbol for the unit itself, \emph{e.g.}~for
-% \cs{metre} with (almost certainly) would be |m|.
-% \item \texttt{power-$n$} The power which a unit is raised to. During
-% initial parsing this will (almost certainly) be positive, but is combined
-% with \texttt{per-$n$} to give a \enquote{fully qualified} power before
-% any formatting takes place
-% \item \texttt{per-$n$} Indicates that \texttt{per} applies to the current
-% unit: stored during initial parsing then combined with \texttt{power-$n$}
-% (and removed from the list) before further work.
-% \item \texttt{qualifier-$n$} Any qualifier which applies to the current
-% unit.
-% \item \texttt{special-$n$} Any \enquote{special effect} to apply to the
-% current unit.
-% \end{itemize}
-%
-% \begin{variable}{\l_@@_sticky_per_bool}

-%
-% User interfaces in tabular constructs are provided using the mechanisms from
-% the \pkg{array} package.
-% \begin{macrocode}
-\RequirePackage { array }
-% \end{macrocode}
-%
-% There is a slight problem with the \pkg{cellspace} package: it also uses
-% \texttt{S} for a column type Here, \texttt{S} seems to make more sense for
-% \pkg{siunitx}, with \texttt{C} used for \pkg{cellspace}. To enable this to
-% work well, the column rewriting code happens \cs{AtBeginDocument}. The
-% \texttt{S} column is deleted from \cs{NC at list} so that no warning appears.
-% \begin{macrocode}
-\AtBeginDocument
- {
- \@ifpackageloaded { cellspace }
- {
- \newcolumntype { C } [ 1 ]
- { > { \bcolumn #1 \@nil } #1 < { \ecolumn } }
- \cs_set:Npn \@@_tmp:w #1 \NC at do S #2 \q_stop
- { \NC at list { #1 #2 } }
- \exp_after:wN \@@_tmp:w \tex_the:D \NC at list \q_stop
- \cs_undefine:N \NC at find@S
- \msg_warning:nnn { siunitx } { moved-cellspace-column } { C }
- \ifcellspace at m
- \def \env at matrix
- {
- \hskip -\arraycolsep
- \let \@ifnextchar \new at ifnextchar
- \array
- {
- * { \c at MaxMatrixCols }
- { > { \bcolumn c \@nil $ } c < { $ \ecolumn } } @ { }
- }
- }
- \fi
- }
- { }
- }
-\msg_new:nnn { siunitx } { moved-cellspace-column }
- { Column~type~for~cellspace~package~moved~to~'#1'. }
-% \end{macrocode}
-%
-% \begin{macro}{\@@_declare_column:Nnn}
-% Creating numerical columns requires that these are declared before anything
-% else in \cs{NC at list}: this is necessary to work with optional arguments.
-% This means a bit of manual effort after the simple declaration of a new
-% column type. The token assigned to the column type is not fixed as this
-% allows the same code to be used in compatibility with version~$2$.
-% \begin{macrocode}
-\cs_new_protected:Npn \@@_declare_column:Nnn #1#2#3
- {
- \newcolumntype {#1} { }
- \cs_set_protected:Npn \@@_tmp:w \NC at do ##1##2 \NC at do #1
- { \NC at list { \NC at do ##1 \NC at do #1 ##2 } }
- \exp_after:wN \@@_tmp:w \tex_the:D \NC at list
- \exp_args:NNc \renewcommand * { NC at rewrite@ #1 } [ 1 ] [ ]
- {
- \@temptokena \expandafter
- {
- \the \@temptokena
- > {#2} c < {#3}
- }
- \NC at find
- }
- }
-% \end{macrocode}
-% When \pkg{mdwtab} is loaded the syntax required is slightly different.
-% \begin{macrocode}
-\AtBeginDocument
- {
- \@ifpackageloaded { mdwtab }
- {
- \cs_set_protected:Npn \@@_declare_column:Nnn #1#2#3
