Discussion
This property doesn’t include whitespace at the beginning of the string. This property is HUGE or –HUGE on overflow, 0 on underflow. This property is 0 if the string doesn’t begin with a valid text representation of a floating-point number.
This method uses formatting information stored in the non-localized value; use an Scanner object for localized scanning of numeric values from a string.
