NAME

rand − pseudo random number generation

SYNOPSIS

include "rand.m";
rand = load Rand Rand->PATH;
 init:    fn(seed: int);
rand:    fn(modulus: int): int;
bigrand: fn(modulus: big): big;

DESCRIPTION

­Init initialises the pseudo-random number generator with seed; subsequent calls to ­rand and ­bigrand return a pseudo-random sequence of integers or bigs respectively, between 0 and modulus−1. ­Modulus should be a non-negative integer; for bigrand, it should be less than 2^53.
