rand(3F)

NAME
     rand, irand, srand - random number generator

SYNOPSIS
     integer iseed, i, irand
     double precision x, rand
     call srand(iseed)
     i = irand( )
     x = rand( )

DESCRIPTION
     irand generates successive pseudo-random integers in the range from 0
     to 2^15-1.  rand generates pseudo-random numbers distributed in [0,
     1.0].  srand uses its integer argument to re-initialize the seed for
     successive invocations of irand and rand.
