Examples of Fraction

cc.redberry.core.tensor.Fraction
This class describes fraction object. Numerator of the fraction can be tensor of any type, without restrictions, but denominator must be a scalar (but not necessary symbol), and constructor throws exception in other case. Fraction returns numerator indices as its indices. Returns @see Tensor @author Dmitry Bolotin @author Stanislav Poslavsky

fraction.Fraction
jmathexpr.arithmetic.equation.rule.Fraction
Rule for eliminating fractions from an equation. @author Elemér Furka
net.imglib2.util.Fraction
Implements the concept of fractions @author Stephan Preibisch
org.apache.commons.lang.math.Fraction

Fraction is a Number implementation that stores fractions accurately.

This class is immutable, and interoperable with most methods that accept a Number.

ptolemy.math.Fraction
A class for representing fractions. Fractions are immutable and maintained in lowest terms, with a positive denominator. Thus, 1/2 and 2/4 are interpreted as different names for the same number. Any fraction with the value zero is expressed as 0/1 in lowest terms.
This class only represents fractions with a determined value, so fractions with a zero in the denominator are not allowed (including 0/0). @author Stephen Neuendorffer, Adam Cataldo @version $Id: Fraction.java,v 1.50 2007/12/07 06:30:31 cxh Exp $ @since Ptolemy II 0.2 @Pt.ProposedRating Green (neuendor) @Pt.AcceptedRating Yellow (cxh)
