RANDOM(3F) UNIX Programmer's Manual RANDOM(3F) NAME random, drandm, irandm - better random number generator SYNOPSIS function irandm (iflag) function random (iflag) double precision function drandm (iflag) DESCRIPTION These functions use random(3) to generate sequences of ran- dom numbers, and should be used rather than the older func- tions described in man 3f rand. If iflag is non-zero, it is used as a new seed for the random number generator, and the first new random value is returned. Irandm returns positive integers in the range 0 through 2147483647 ( 2**31-1). Random and drandm return values in the range 0. through 1.0 by dividing the integer random number from random(3) by 2147483647 .
