.TH RAND 2
.SH NAME
rand \- pseudo random number generation
.SH SYNOPSIS
.EX
include "rand.m";
rand = load Rand Rand->PATH;
init: fn(seed: int);
rand: fn(modulus: int): int;
bigrand: fn(modulus: big): big;
.EE
.SH DESCRIPTION
.B Init
initialises the pseudo-random number generator
with
.IR seed ;
subsequent calls to
.B rand
and
.B bigrand
return a pseudo-random sequence of integers
or bigs respectively, between 0 and
.IR modulus \-1.
.I Modulus
should be a non-negative integer;
for
.BR bigrand ,
it should be less than 2^53.

.SH BUGS
The quality of the algorithm currently used is questionable.
