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:

principles to implementation. J. ACM 48, 5 (September 2001), 1038-1068.
