Package eu.bandm.sig.adlib2

Class IntFraction

java.lang.Object
eu.bandm.sig.adlib2.IntFraction
All Implemented Interfaces:
Comparable<IntFraction>
public class IntFraction extends Object implements Comparable<IntFraction>
Representation of fractions.

A fraction is a pair of values, namely the numerator and the denominator, respectively, and represents their quotient.

This class provides fractional arithmetic operations. Note that those are not optimized for high performance or low memory usage. Thus, computations implemented by this class should be used only at construction time of a network. For realtime fractional computations, use IntSignalSourceFraction instead.
