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 _r_a_n_d_o_m(3) to generate sequences of ran-
     dom numbers, and should be used rather than the older func-
     tions described in _m_a_n _3_f _r_a_n_d. If _i_f_l_a_g is non-zero, it is
     used as a new seed for the random number generator, and the
     first new random value is returned.

     _I_r_a_n_d_m returns positive integers in the range 0 through
     2147483647 ( 2**31-1).  _R_a_n_d_o_m and _d_r_a_n_d_m return values in
     the range 0. through 1.0 by dividing the integer random
     number from _r_a_n_d_o_m(3) by 2147483647 .
