cLCG32 Class Reference
#include <clcg32.h>
Description
Implements a 32-bit (2^31-2 cycle length) linear congruential random number generator.
- Range: 1 ... 2^31-2
- Period length: 2^31-2
- Method: x=(x * 7^5) mod (2^31-1)
- Required hardware: exactly 32-bit integer aritmetics
- To check: if x[0]=1 then x[10000]=1,043,618,065
