com.singularsys.extensions.field.implementations.RationalWithInfinity

All Implemented Interfaces:

Serializable, Comparable<RationalWithInfinity>

public class RationalWithInfinity
extends Number
implements Comparable<RationalWithInfinity>

A rational number represented as the quotient of two BigIntegers. An immutable type.

Note if using Rational numbers with the PrintVisitor a special rule RationalDivisionPrintRule is needed to ensure divisions are correctly printed. This can be added with

 jep.getPrintVisitor().addSpecialRule(jep.getOperatorTable().getDivide(),
                        new RationalDivisionPrintRule());
