Discussion

This property doesn’t include whitespace at the beginning of the string. This property is HUGE_VAL or –HUGE_VAL on overflow, 0.0 on underflow. This property is 0.0 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.
