Package dev.nm.stat.random.rng.univariate.uniform

Class UniformRNG

java.lang.Object
dev.nm.stat.random.rng.univariate.uniform.UniformRNG
All Implemented Interfaces:
RandomLongGenerator, RandomNumberGenerator, Seedable
public class UniformRNG extends Object implements RandomLongGenerator
A pseudo uniform random number generator samples numbers from the unit interval, [0, 1], in such a way that there are equal probabilities of them falling in any same length sub-interval. Sampling from the unit interval is the most basic building block of most pseudo random number generation algorithms.
