Java - Float longValue() method

---

---

Description

The Java Float longValue() method returns the long value of this Float object.

Declaration

Following is the declaration for java.lang.Float.longValue() method

public long longValue()

Parameters

NA

Return Value

This method returns the long value represented by this object.

Exception

NA

Example 1

The following example shows the usage of Float longValue() method to get a long primitive value of given positive Float object. We've initialized a Float object with a given positive long value. Then using longValue() method, we're printing its value.

package com.tutorialspoint;
public class FloatDemo {
   public static void main(String[] args) {
      Float d = new Float("15.30");
   
      //return the long value
      System.out.println("Value = " + d.longValue());
   }
} 

Output

Let us compile and run the above program, this will produce the following result −

Value = 15

Example 2

The following example shows the usage of Float longValue() method to get a long primitive value of given negative Float object. We've initialized a Float object with a given positive long value. Then using longValue() method, we're printing its value.

package com.tutorialspoint;
public class FloatDemo {
   public static void main(String[] args) {

      Float d = new Float("-15.30");
   
      //return the long value
      System.out.println("Value = " + d.longValue());
   }
} 

Output

Let us compile and run the above program, this will produce the following result −

Value = -15

Example 3

The following example shows the usage of Float longValue() method to get a long primitive value of given negative Float object of zero value. We've initialized a Float object with a given positive long value. Then using longValue() method, we're printing its value.

package com.tutorialspoint;
public class FloatDemo {
   public static void main(String[] args) {

      Float d = new Float("-0.0");
   
      //return the long value
      System.out.println("Value = " + d.longValue());
   }
} 

Output

Let us compile and run the above program, this will produce the following result −

Value = 0

Example 4

The following example shows the usage of Float longValue() method to get a long primitive value of given positive Float object of zero value. We've initialized a Float object with a given positive long value. Then using longValue() method, we're printing its value.

package com.tutorialspoint;
public class FloatDemo {
   public static void main(String[] args) {
      Float d = new Float("+0.0");
   
      //return the long value
      System.out.println("Value = " + d.longValue()); 
   }
} 

Output

Let us compile and run the above program, this will produce the following result −

Value = 0
