Float longValue() in Java with Examples Last Updated : 11 Jul, 2025 Comments Improve Suggest changes Like Article Like Report 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: 1022 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 Reference: https://docs.oracle.com/javase/7/docs/api/java/lang/Float.html#longValue() Comment More infoAdvertise with us Next Article Float shortValue() method in Java with examples G gopaldave Follow Improve Article Tags : Java java-basics Java-lang package Java-Functions Java-Float +1 More Practice Tags : Java Similar Reads Float shortValue() method in Java with examples The shortValue() method in Float Class is a built-in method in Java which returns the value specified by calling the object as short after typecasting.Syntax: public short shortValue() Return Value: It return the value of FloatObject as short.Below programs illustrate shortValue() method in Java: Pr 2 min read Float shortValue() method in Java with examples The shortValue() method in Float Class is a built-in method in Java which returns the value specified by calling the object as short after typecasting.Syntax: public short shortValue() Return Value: It return the value of FloatObject as short.Below programs illustrate shortValue() method in Java: Pr 2 min read Float parseFloat() method in Java with examples The parseFloat() method in Float Class is a built in method in Java that returns a new float initialized to the value represented by the specified String, as done by the valueOf method of class Float.
