<div class="block"><p>Extends <a href="http://docs.oracle.com/javase/1.5.0/docs/api/java/math/package-summary.html?is-external=true"><code>java.math</code></a> for business mathematical classes.
This package is intended for business mathematical use, not scientific use.
See <a href="http://commons.apache.org/math/">Commons Math</a> for a more complete set of mathematical classes.
These classes are immutable, and therefore thread-safe.</p>
<p>Although Commons Math also exists, some basic mathematical functions are contained within Lang.
These include classes to a <a href="../../../../../org/apache/commons/lang3/math/Fraction.html" title="class in org.apache.commons.lang3.math"><code>Fraction</code></a> class, various utilities for random numbers, and the flagship class, <a href="../../../../../org/apache/commons/lang3/math/NumberUtils.html" title="class in org.apache.commons.lang3.math"><code>NumberUtils</code></a> which contains a handful of classic number functions.</p>
<p>There are two aspects of this package that should be highlighted.
The first is <a href="../../../../../org/apache/commons/lang3/math/NumberUtils.html#createNumber-java.lang.String-"><code>NumberUtils.createNumber(String)</code></a>, a method which does its best to convert a String into a <a href="http://docs.oracle.com/javase/1.5.0/docs/api/java/lang/Number.html?is-external=true" title="class or interface in java.lang"><code>Number</code></a> object.
You have no idea what type of Number it will return, so you should call the relevant <code>xxxValue</code> method when you reach the point of needing a number.
NumberUtils also has a related <a href="../../../../../org/apache/commons/lang3/math/NumberUtils.html#isCreatable-java.lang.String-"><code>NumberUtils.isCreatable(String)</code></a> method.</p></div>
