rand(3C)                (BSD Compatibility Package)                rand(3C)


   NAME
         rand, srand - simple random number generator

   SYNOPSIS
         cc [ flag... ] file ... -lucb

         srand(seed)
         int seed;

         rand()

   DESCRIPTION
         rand uses a multiplicative congruential random number generator with
         period 2**32 to return successive pseudo-random numbers in the range
         from 0 to (2**31)-1.

         srand can be called at any time to reset the random-number generator
         to a random starting point.  The generator is initially seeded with a
         value of 1.

   SEE ALSO
         random(3).

         drand48(2), drand(3C), rand(3C), srand(3C) in the Programmer's
         Reference Manual.

   NOTES
         The spectral properties of rand leave a great deal to be desired.
         drand48(2) and random(3) provide much better, though more elaborate,
         random-number generators.

         The low bits of the numbers generated are not very random; use the
         middle bits.  In particular the lowest bit alternates between 0 and
         1.
