de.grogra.vecmath.Range

public class Range
extends java.lang.Object

This class implements interval arithmetic. Each range is an interval [a,b] with a <= b. Some operations for interval arithmetic are implemented. In general those operations expect an additional parameter out to store the result. For some information on interval arithmetic read: T. Hickey, Q. Ju, and M. H. Van Emden. 2001. Interval arithmetic: From principles to implementation. J. ACM 48, 5 (September 2001), 1038-1068. DOI=10.1145/502102.502106 http://doi.acm.org/10.1145/502102.502106
