Instance Property


The floating-point value of the string as a double.


var doubleValue: Double { get }


This property doesn’t include any 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 property uses formatting information stored in the non-localized value; use an Scanner object for localized scanning of numeric values from a string.
