RAND(3F)							      RAND(3F)

NAME
       rand, drand, irand - return random values

SYNOPSIS
       integer*4 function irand (iflag)

       real*4 function rand (iflag)

       real*8 function drand (iflag)

       integer*4 iflag

DESCRIPTION
       These functions use random(3) to generate sequences of random numbers.

       If  iflag  is  0,  the  generator returns the next random number in the
       sequence.

       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.   The
       three functions share the same 256-byte state array.

       irand returns positive integers in the range 0 through 2147483647.

       rand and drand return values in the range 0.0 through 1.0.

       The only advantage of these functions is that they are widely available
       on UNIX systems. For  better  random  number  generators,  see  lcrans,
       addrans, and shufrans in the Numerical Computation Guide.
