Class DoubleNumberFactory

java.lang.Object
com.singularsys.jep.standard.DoubleNumberFactory
All Implemented Interfaces:
JepComponent, NumberFactory, Serializable
public class DoubleNumberFactory extends Object implements NumberFactory
Default class for creating number objects. This class can be replaced by other NumberFactory implementations if other number types are required.

The results from the different methods can be inconsistent. The createNumber(Number) method when passed an Integer returns an Integer. See StrictDoubleNumberFactory for a stricter version where all methods return Double.
