Float longValue() in Java with Examples

Last Updated : 11 Jul, 2025

The java.lang.Float.longValue() method in Float Class is a built in method in Java that returns the value specified by the calling object as long after type casting. Syntax:

public long longValue()

Parameters: It takes no parameters. Return type: It returns an long value i.e. the type casted value of the FloatObject. Below is the implementation of the above method. Program 1:

Java

// Java Code to implement
// longValue() method of Float class

class GFG {

    // Driver method
    public static void main(String[] args)
    {

        // creating a Float object
        Float d = new Float(1022);

        // longValue() method of Float class
        // typecast the value
        long output = d.longValue();

        // printing the output
        System.out.println(output);
    }
}

Output:

Program 2:

Java

// Java Code to implement
// longValue() method of Float class

class GFG {

    // Driver method
    public static void main(String[] args)
    {

        // creating a Float object
        Float d = new Float(-1023.23);

        // longValue() method of Float class
        // typecast the value
        long output = d.longValue();

        // printing the output
        System.out.println(output);
    }
}

Output:

-1023
