Class UniformRng

java.lang.Object

com.numericalmethod.suanshu.stats.random.univariate.uniform.UniformRng

All Implemented Interfaces:

RandomLongGenerator, RandomNumberGenerator, java.io.Serializable

public class UniformRng
extends java.lang.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.
