Rand for Elektra.
void elektraRand | ( | int32_t * | seed | ) |
Non cryptographic pseudo random number generator By Ray Gardner www8.cs.umu.se/~isak/snippets/rg_rand.c.
based on "Random Number Generators: Good Ones Are Hard to Find", S.K. Park and K.W. Miller, Communications of the ACM 31:10 (Oct 1988), and "Two Fast Implementations of the 'Minimal Standard' Random Number Generator", David G. Carta, Comm. ACM 33, 1 (Jan 1990), p. 87-88
linear congruential generator f(z) = 16807 z mod (2 ** 31 - 1)
uses L. Schrage's method to avoid overflow problems
Make sure the initial seed is: 0 < seed < ELEKTRARANDMAX
