Java Float longValue() Method

Description

The Java Float longValue() method returns value of this Float as a long (by casting to type long).

Declaration

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

public long longValue()

Parameters

NA

Return Value

This method returns the float value represented by this object converted to type long.

Exception

NA

Getting long value from Float Objet having Positive Value Example

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

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

Output

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

Value = 15

Getting long value from Float Objet having Negative Value Example

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

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

Output

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

Value = -15

Getting long value from Float Objet having Negative Zero Value Example

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

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

Output

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

Value = 0

Getting long value from Float Objet having Positive Zero Value Example

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

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

Output

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

Value = 0
