java.math for business mathematical classes.See: Description
| Class | Description | 
|---|---|
| Fraction | Fractionis aNumberimplementation that
 stores fractions accurately. | 
| IEEE754rUtils | Provides IEEE-754r variants of NumberUtils methods. | 
| NumberUtils | Provides extra functionality for Java Number classes. | 
Extends java.math for business mathematical classes.
 This package is intended for business mathematical use, not scientific use.
 See Commons Math for a more complete set of mathematical classes.
 These classes are immutable, and therefore thread-safe.
Although Commons Math also exists, some basic mathematical functions are contained within Lang.
 These include classes to a Fraction class, various utilities for random numbers, and the flagship class, NumberUtils which contains a handful of classic number functions.
There are two aspects of this package that should be highlighted.
 The first is NumberUtils.createNumber(String), a method which does its best to convert a String into a Number object.
 You have no idea what type of Number it will return, so you should call the relevant xxxValue method when you reach the point of needing a number.
 NumberUtils also has a related NumberUtils.isCreatable(String) method.
