double kjb_rand(void);

DESCRIPTION

This routine returns a random double between 0 and 1 using erand48(). The seeding of the random number generator is normally exposed to the user through the option "seed". It may also be seeded using the routine kjb_seed_rand(). If the generator is not seeded, then a default seed is used (zeros). The form of the seed option value is <value_1>:<value_2>, where value_1 and value_2 are either integers, or the special value "*", which gets converted to the time of day as returned by the routine time(NULL). This routine sets up a different stream of random numbers from kjb_rand_2. In general, the library code uses kjb_rand_2, with kjb_rand being the normal choice for higher level code. This random number generator is restartable from the seed value obtained by get_rand_seed().
