Constructor & Destructor Documentation

TRNG::LCG32::LCG32 unsigned long    a_ = 69069ul,
unsigned long    b_ = 1ul,
long    seed_ = 0l
 

The constructor's default values implement a pseudo random number generator used on VAX. This generator has a period of . This generator is just a toy. Its period is too short and it has some bad statistical properties.

Parameters:
a_  multiplier
b_  additive constant
seed_  default seed
