Examples and Tests:

DRAND48_TEST shows how to use the standard library routines SRAND48 to set the seed and DRAND48 to return random real numbers in [0,1].

RAND_DEFECT_TEST points out a minor problem with generating real numbers by calling TIME to seed SRAND and then dividing RAND() by RANDMAX, namely, the first value returned will be about the same every time you run the program:

RAND_TEST shows how to use the standard library routines SRAND to set the seed and RAND to return random integers which can be scaled to real numbers in [0,1].

RANDOM_TEST shows how to use the standard library routines SRANDOM to set the seed and RANDOM to return random integers which can be scaled to real numbers in [0,1].
