Class CurvedBoundedDistribution

java.lang.Object

squidpony.squidmath.IDistribution.SimpleDistribution

squidpony.squidmath.CurvedBoundedDistribution

All Implemented Interfaces:

IDistribution

public class CurvedBoundedDistribution
extends IDistribution.SimpleDistribution
implements IDistribution

An IDistribution that allows a parameter to determine how many calls to IRNG.nextDouble() to make and average whenever a double is requested. When this parameter degree is 1, this is uniform; when it is 2, this is a triangular distribution, and when it is 3 or more it is an increasingly centralized bell curve. The average value is always very close to 0.5, and the bounds are the same as IRNG.nextDouble().

getMean

public double getMean()

Gets the mean value of this distribution (0.5).

Specified by:

getMean in interface IDistribution

Overrides:

getMean in class IDistribution.SimpleDistribution

Returns:

the mean value of this distribution (0.5)
