Last Updated : 20 Jun, 2018

The java.lang.Number.longValue() is an inbuilt method in java that returns the value of the specified number casted to long data type. This may involve rounding or truncation.

Syntax:

public abstract long longValue()

Parameters: This method does not accepts any parameter.

Return value: This method returns the numeric value represented by this object after conversion to type long.

Below program illustrate the Number.longValue() method:

Program 1:

// java program to demonstrate 
// Number.longValue() method 
public class gfg { 
  
    public static void main(String[] args) 
    { 
  
        // number as float 
        Float x = new Float(127483456f); 
        // print the value as long 
        System.out.println(x.longValue()); 
  
        // number as double 
        Double y = new Double(78549876); 
        // print the value as long 
        System.out.println(y.longValue()); 
    } 
} 

Output:

127483456
78549876

Program 2:

// java program to demonstrate 
// Number.longValue() method 
public class gfg { 
  
    public static void main(String[] args) 
    { 
  
        // number as float 
        Float x = new Float(127f); 
        // print the value as long 
        System.out.println(x.longValue()); 
  
        // number as double 
        Double y = new Double(76.23); 
        // print the value as long 
        System.out.println(y.longValue()); 
    } 
} 

Output:

127
76
