Problem
How do Math.h++ random number classes generate random numbers?
Cause
Action
The random number generator in the class RWRandGenerator is taken from the ran1 example in Numerical Recipes. It is a slightly modified additive congruential generator. This algorithm is an improvement over many implementations of the ANSI C random number generator rand(), which is almost always a linear congruential generator.

Starting in Math 6.0, you can define your own uniform random number generator if desired.
