% \subsection{Introduction}
%
% Dealing with the PDF format, there is sometimes the need to write
% some low level PDF stuff. In case of numbers, the numbers can
% arise from user input (e.g. color or transparency specifications)
% or can be calculated. For example, \hologo{LaTeX}'s \cs{strip@pt}
% makes a good job to output a real number. It automatically suppresses
% the decimal part if the number is an integer. However it leaves
% a leading zero for numbers greater zero and smaller one.
% Thus the package provides macros that can be used with different
% formats, even with \hologo{iniTeX} and generates numbers that
% are valid numbers of the PDF format and whose length is minimal.
%
% \subsection{Usage}
%
% The package \xpackage{thepdfnumber} can be used with \hologo{LaTeX},
% \hologo{plainTeX} or even with \hologo{iniTeX}:
% \begin{quote}
% |\RequirePackage{thepdfnumber}| \textit{\% \hologo{LaTeX}}\\
% |\input thepdfnumber.sty| \textit{\% \hologo{plainTeX}/\hologo{iniTeX}}
% \end{quote}
% The package does not need and have package options.
%
% \subsection{User macros}
%
% All user macros are expandable in exact two expansion steps.
%
% \begin{declcs}{thepdfnumber} \M{number}
% \end{declcs}
% Macro \cs{thepdfnumber} takes a number
% as argument and expands to a minimal representation of that number.
% Some examples:
% \begin{quote}
% \begin{tabular}{r@{.: }>{\ttfamily}l@{ $\rightarrow$\ }>{\ttfamily}l@{}}
% 1& +123 & 123\\
% 2& --123 & 123\\
% 3& -01 & -1\\
% 4& 0045 & 45\\
% 5& 1.0 & 1\\
% 6& 1.20 & 1.2\\
% 7& 0.0 & 0\\
% 8& 0.78 & .78\\
% 9& +012.340 & 12.34\\
% \end{tabular}
% \end{quote}
% It reduces the length of the number representation:
% \begin{itemize}
% \item The signs are collapsed and only one minus sign
% is output if the number is negative (see examples 1, 2, 3, 9).
% \item Leading zeros are removed (4, 8, 9) unless the number is zero (7).
% \item The decimal part is omitted, if the number is an integer (5, 7).
% \item Trailing zeros from the decimal part are stripped (5, 6, 7, 9).
% \end{itemize}
% The resulting number representation can be caught with one of the
% following Perl regular expressions:
% \begin{itemize}
% \item |^0$| (zero)
% \item |^-?[1-9][0-9]*$| (integer)
% \item |^-?[0-9]*\.[0-9]*[1-9]$| (real)
% \end{itemize}
% This is a valid numeric object of the PDF specification \cite[``7.3.3~Numeric Objects'']{pdfspec-iso32000-1}.
%
% \begin{declcs}{thepdfnumberNormZeroOne}
% \end{declcs}
% There are various places in the PDF specification where the
% number is in the domain 0.0 upto 1.0. Macro thepdfnumberNormZeroOne
% automatically adjusts the number to fit into that range. Negative
% numbers are mapped to |0| and numbers greater than one are
% replaced by |1|. Thus the result fits one of the following regular
% expressions:
% \begin{itemize}
% \item |^0$|
% \item |^\.[0-9]*[1-9]$|
% \item |^1$|
% \end{itemize}
% Examples:
% \begin{quote}
% \begin{tabular}{@{}>{\ttfamily}l@{ $\rightarrow$\ }>{\ttfamily}l@{}}
% -456 & 0\\
% -0.001 & 0\\
% 0.0 & 0\\
% 0.010 & .01\\
% 0.456 & .456\\
% 1.0 & 1\\
% 01.001 & 1\\
% 4 & 1\\
% \end{tabular}
% \end{quote}
%
% \subsection{Input number}
%
% The user macros expect a number as argument. The number can either
% be given explicitly or as macro that expands in one step
% to an explicit number, because the first token of the argument
% is expanded once.
%
% The explicit number consists of
% \begin{itemize}
% \item optional signs `\texttt{+}' and `\texttt{-}',
% \item digits `\texttt{0}' upto `\texttt{9}' and
% \item an optional dot `\texttt{.}'.
% \end{itemize}
% All tokens must have catcode 12 (other), the default catcodes
% for these characters in \hologo{LaTeX}, \hologo{plainTeX} or
% \hologo{iniTeX}. As Perl regular expression the number is expected
% in one of the following forms:
% \begin{itemize}
% \item |^[+-]*[0-9]+$|
% \item |^[+-]*[0-9]*\.[0-9]*$|
% \end{itemize}
% At least one digit or the dot must be present.
%
% \subsection{Error handling}
%
% The package is not intended for validating numbers or to
% decide if an argument is a number. Therefore it is an usage
% error to use the user macros with arguments that are not
% explicit numbers as specified in the previous sections.
% Nevertheless some error conditions are sometimes recognized.
% Errors are given in form of an undefined command sequence.
% It is the only way to notify \hologo{TeX} in expandable context.
% Expanding to some error text would invalidate the output.
% Currently the following errors are thrown:
% \begin{description}
% \item[\cs{thepdfnumber@ErrorEndMarker}:]
% Internally the argument parsing uses an end marker that
% is never called directly. If it is called with valid
% user input, then this is a bug. Otherwise it means the user input
% contains nasty stuff.
% \item[\cs{thepdfnumber@ErrorUnexpectedEnd}:] The macros expect at least one digit
% or the dot, otherwise if the argument is empty or only contains
% signs, then this error is called.
% \item[\cs{thepdfnumber@ErrorInvalidToken}:] It is called if the number
% contains other tokens than signs, digits or the dot or the
% token at the wrong place (e.g. a sign after a digit).
% In case of \cs{thepdfnumberNormZeroOne} this error condition might
% not always be detected, because the number parsing might stop
% at an early point, when the result is already clear (e.g.
% if the number is negative or will be greater than one).
% \item[Improper alphabetic constant:] This error might be
% thrown by \hologo{TeX}, if the number contains
% command tokens instead of characters.
