Float doubleValue() method in Java with examples

0 1 1 minute read

The doubleValue() method of Float class is a built in method to return the value specified by the calling object as double after type casting. Syntax:

FloatObject.doubleValue()

Return Value: It return the double value of this Float object. Below programs illustrate doubleValue() method in Java: Program 1:

Java

// Java code to demonstrate
// Float doubleValue() method
 
class GFG {
    public static void main(String[] args)
    {
 
        // Float value
        float a = 17.65f;
 
        // wrapping the Float value
        // in the wrapper class Float
        Float b = new Float(a);
 
        // doubleValue of the Float Object
        double output = b.doubleValue();
 
        // print doubling the output
        System.out.println("Float value of "
                           + b + " is : " + output);
    }
}

Output:

Float value of 17.65 is : 17.649999618530273

Program 2:

Java

// Java code to demonstrate
// Float doubleValue() method
 
class GFG {
    public static void main(String[] args)
    {
 
        // Float value
        float a = 6.0f;
 
        // wrapping the Float value
        // in the wrapper class Float
        Float b = new Float(a);
 
        // doubleValue of the Float Object
        double output = b.doubleValue();
 
        // print doubling the output
        System.out.println("Float value of "
                           + b + " is : " + output);
    }
}
