#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
