RAND(2) System Calls Manual RAND(2)

rand - pseudo random number generation

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

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.
