-The rangen Package
-
-The rangen package is a package that generates random integers,
-rational numbers, and decimal number. Actually, the package uses the
-lcg package (by Erich Janka) to generate random integers, while
-rangen builds rational numbers and decimal numbers from the
-generated integers. My purpose in writing this package was to be
-able to create random questions for the quizzes of exerquiz (part of
-AeB). Indeed, that is what you can do with this package: Write a
-quiz question based on a template (for example, differentiate
-$\a x^{\n}$ , where \a and \n are RVs (random variables) generated with
-rangen); determine if the user input is correct; and display the
-correct answer to the question.
-
-Beta Testers wanted: The package is still in development. I would
-invite anyone interested to test the package, looking for bugs.
-Also, suggested features would be appreciated.
-
-The rangen package requires the insdljs package from AeB. The
-package can be used without exerquiz, perhaps there are some
-applications to the generation of random numbers. As pointed out in
-the documentation, the fp package can be used to manipulate the
-numbers created by rangen.

-Comments and suggestions are always gratefully accepted and seriously
-considered.

-% \section{Introduction}
-%
-% This package provides some commands for creating randomly generated integers, rational,
-% and real numbers. There are options for specifying constraints on the generation of the numbers.
-% Companion JavaScript functions are developed to use these random numbers as part of a
-% question in a \texttt{shortquiz} or \texttt{quiz}. The syntax of this package can be used
-% to pose number-related questions, the JavaScript can be used to create the answer to the
-% question based on a formula. You'll have to see it to believe it.
-%
-% \section{The Main Code}
-%
-% \subsection{Declare Options}
-%
-% This package has not options, but uses the really nice \textsf{lcg} Package,
-% by Erich Janka (\texttt{janka@utanet.at}). We simply pass any
-% options on to \textsf{lcd}.
-% \begin{macrocode}
-\newcount\seedCnt
-\DeclareOption{testmode}{%
- \InputIfFileExists{\jobname.seed}{}{\def\thisseed{1}}%
- \PassOptionsToPackage{seed=\thisseed}{lcg}%
- \AtEndOfPackage{\reseedEachRun}%
-}
-\def\reseedEachRun{%
- \seedCnt=\thisseed
- \advance\seedCnt1\relax
- \newwrite \rngWrite
- \immediate\openout\rngWrite \jobname.seed
- \immediate\write\rngWrite{\string\def\string\thisseed{\the\seedCnt}}
- \immediate\closeout\rngWrite
-}
-\def\RNG@Dec{.}
-\DeclareOption*{\PassOptionsToPackage{\CurrentOption}{lcg}}
-\ProcessOptions
-\RequirePackage{lcg}[2008/09/10]
-% \end{macrocode}
-% Save the seed value so we can reproduce the same pseudo-random number sequence.
-% \begin{macrocode}
-\edef\rng@saveSeed{\the\cr@nd}
-% \end{macrocode}
-% There are three data types: Integer, Rational, and Real. The following macros
-% gives each of these types a numerical value, 0, 1 and 2, respectively.
-% \begin{macrocode}
-\newcount\loopCnt
-\def\maxLoopLimit{10}
-\def\typeCodeForz{0}
-\def\typeCodeForq{1}

-% \end{macrocode}
-% Some scratch count registers
-% \begin{macrocode}
-\newcount\rng@cnta
-\newcount\rng@cntb
-% \end{macrocode}
-% A random variable is specified using a control sequence, e.g. \cs{a}. The following macro
-% extracts the underlying name of the command, e.g. \verb+\@gtVarName{\a}+ expands to \texttt{a},
-% and returns the name as the expansion of the macro \cs{@varName}.
-% \begin{macrocode}
-\def\@getVarName#1{%
- \edef\@varName{\expandafter\@gobble\string#1}%
-}
-% \end{macrocode}
-% The command \cs{@getVarType} takes one argument, a random variable, e.g., \cs{a}. This
-% command defines a macro \cs{varType} which expands to the data type the random variable is.

-% \begin{macro}{\reduceFrac}
-% Reduce a fraction to lowest terms. The first argument is the numerator and the second

-% the numerator in the \cs{rfNumer} command, and the denominator in the \cs{rfDenom} command.
-% For example,
-%\begin{verbatim}
-%\defineQ\a{1}{3}\defineQ\b{3}{5}\RNGadd\a\b
-%\makeatletter
-%The sum of $\frac{\nOf\a}{\dOf\a} + \frac{\nOf\b}{\dOf\b}
