Variable Documentation

Random class provides a set of Real and Integer linear congruential random operations.

Note, this implementation does not produce very high-quality randomness. The methods here are good for understanding general principles, but for better numerical results see Press, et. al., "Numerical Recipes in C", Cambridge University Press, 198
