org.openl.rules.helpers.DoubleRange

All Implemented Interfaces:

INumberRange

public class DoubleRange
extends Object
implements INumberRange

The DoubleRange class stores range of floats. Examples : "1.2-3", "2 .. 4", "123.456 ... 1000.00001" (Important: using of ".." and "..." requires spaces between numbers and separator).
