drand48, erand48, jrand48, lcong48, lrand48, mrand48, nrand48, seed48, Unless lcong48() is invoked, the multiplier value a and the addend value c are. a = 0x5DEECE66D c = 0xB. The value returned by any of the functions drand48() , erand48(), lrand48(), nrand48(), mrand48() or jrand48() is computed by first  SYNOPSIS - DESCRIPTION. C/™ provides storage to save the most recent bit integer value of the sequence, X(i). This storage is shared by the drand48(), lrand48() and mrand48() .

As for which function you should use, the C standard rand() function is the generator with the following formula (according to man 3 drand48). @(#)drandc */ /*LINTLIBRARY*/ /* * drand48, etc. pseudo-random number generator * This implementation assumes unsigned short integers of at least. DRAND48 - obtain double precision random number. double drand48(); r = drand48(); "drand48" returns a pseudo-random number in the range [,). expl c lib seed48 expl c lib srand48 expl c lib erand48 expl c lib jrand48 expl c lib.

The drand48() and erand48() functions return nonnegative double-precision floating-point values uniformly Unless lcong48() is called, a and c are given by.
