Double Range Validator

See Also | Tutorials

A Double Range validator is typically used to validate that the value of a component does not exceed the standard range of the Java double data type. This data type represents a double floating-point number that ranges from ±439E-324 to ±1.7976931348623157E+308. Typically, the way you add a validator to a JavaServer Faces component is to edit the component's validator property, which provides a drop-down list from which you can select a validator.
