Foil 12 Simple Random Number Generator

From CPS615 Foils -- set D:Statistics and Random Numbers CPS615 Basic Simulation Track for Computational Science -- Fall Semester 95. by Geoffrey C. Fox
1 Take the choice:
2 m = 231
3 a = 1103515245
4 c = 12345
5 Implemented in C as (64 bit)
6 newran = [a*oldran+c] & MASK
7 floatran = newran/2147483648.0
8 oldran = newran
9 floatran is uniformly distributed in [0,1]
10 MASK has lower 31 bits = 1and all higher bits = 0
11 This intuitively says that lower order bits of a complex multiplication are "essentially" random
