LaTeX pseudo random number generator

5 Comments

A random generator might come in handy at some point. The lcg package provides exactly that.

All you have to do is load the package with options if needed.

1
\usepackage[option1, option2, ...]{lcg}

Available options:

first: lower bound (\geq-2^{31}+1),
last: upper bound (\leq2^{31}-1),
counter: name of the random number (overwritten if existing),
seed: starting value for reproducibility, and
quiet: suppress log and console output.

Without specifying boundaries, a random number will be generated in the interval [1, 2^{31}-1].

The \rand command produces a new random number and \arabic{rand} writes the number to the document, assuming you are using the default counter name “rand”.

Example code for a random number between -100 and 100. The code also defines the macro random for simplification.

\usepackage[first=-100, last=100]{lcg}
\newcommand{\random}{\rand\arabic{rand}}
...
\random

Similarly, roman random numbers can be generated using \roman{rand} instead of \arabic{rand}.

You can find the package as well as the documentation here.
