> The method _isNumber_ uses _Double.parseDouble(s)_ to infer whether the input
> string value is a number. _Double.parseDouble(s)_ skips tail zero or tail
> whitespace{_}.{_} For instance , string "77123 " and " 7112324" are valid
> input values. But when it comes to method _isConvertFloatPrecisionLack(s) ,_
> a _NumberFormatException_ occurs as whitespace is not allow in method
> _Long.parseLong(s)._
> 1. Add two values in _isNumberTest_ , passed.
