RAND(3F)                             BSD                              RAND(3F)



NAME
     rand, drand, irand - return random values

SYNOPSIS
     function irand (iflag)

     function rand (iflag)

     double precision function drand (iflag)

DESCRIPTION
     The newer random(3f) should be used in new applications; rand remains for
     compatibilty.

     These functions use rand(3C) to generate sequences of random numbers.  If
     iflag is 1, the generator is restarted and the first random value is
     returned.  If iflag is otherwise nonzero, it is used as a new seed for
     the random number generator, and the first new random value is returned.

     irand returns positive integers in the range 0 through 2147483647.  rand
     and drand return values in the range 0. through 1.0 .
