Detailed Description

The following routines produce random non-negative integers in the range 0.

2^(w-1) -1, where w is the word size available for integers, e.g 32 for Intel machines and 64 for Alpha machines Note that the numbers generated by this random number generator are repeatable This generator was originally written by Allen Van Gelder and is based on Knuth Vol 2

setrand/1

class setrand/1

setrand(+ Key)

Use a term of the form rand(X,Y,Z) to set a new state for the random number generator The integer X must be in the range [1...30269), the integer Y must be in the range [1...30307), and the integer Z must be in the range [1...30323)
