Class RadicandBounds

java.lang.Object
  org.openmali.number.RadicandBounds

public class RadicandBounds
extends java.lang.Object

This class stores a cache of known (inclusive) rational bounds for sqrt radicands. We keep a cache becuase we don't expect a program to have that many different options of radicands used. NOT IMPLEMENTED: improving bounds at runtime using bisection methodology
