random(3f) — RISC
NAME
random, drandm, irandm − better random number generator
SYNTAX
function irandm ( iflag ) function random ( iflag ) double precision function drandm ( iflag )
DESCRIPTION
These functions use the random function to generate sequences of random numbers, and should be used rather than the older functions described in rand() If iflag is nonzero, it is used as a new seed for the random number generator, and the first new random value is returned.
The irandm function returns positive integers in the range 0 through 2147483647 (2**31−1). The random and drandm functions return values in the range 0. through 1.0 by dividing the integer random number from random() by 2147483647 .
