public class RoundedDistribution
extends DiscreteDistribution

Rounded Distribution

Meaning:	The "rounded distribution" is a discrete distribution that converts the value obtained from a continuous ("base") distribution to an integer value using the rint() function from the Java Math package. rint(x) returns the integer value nearest to $x$ (e.g., rint(1.4) is 1.0 and rint(1.6) is 2.0).
Parameters:	continuous base distribution $f(x)$ (DF $F(x)$)
Distribution:	$P(X=i) = F(i+\frac{1}{2})-F(i-\frac{1}{2})$
Parser example:	[...].Distribution = RoundedDistribution [...].Distribution.BaseDist = NegExp [...].Distribution.BaseDist.Mean = 2.5
