> The {{NumberUtils.createNumber()}} method fails to check for multiple trailing characters, and as a result, it returns a value even though {{NumberUtils.isNumber()}} indicates that it should not.  For example:
> {code}
> boolean isNumber = NumberUtils.isNumber("81.5514DD");   // returns false
> Number numValue = NumberUtils.createNumber("81.5514DD");  // returns a Double value, 81.5514
> {code}
> I would expect the {{createNumber()}} method to throw a {{NumberFormatException}} in this case.
