Class RationalInt

java.lang.Object

de.uni_kl.cs.discodnc.numbers.implementations.RationalInt

All Implemented Interfaces:

Num

public class RationalInt
extends java.lang.Object
implements Num

Wrapper class around org.apache.commons.math3.fraction.Fraction introducing special values like positive / negative infinity and NaN as well as operators like min, max, ==, >, >=, <, and <= that are not part of Fraction but needed by the network calculator.

For the ease of converting from the primitive data type double to Fraction objects, copy by value semantic are is applied.
