Java - Long floatValue() method
Description
The Java Long floatValue() method returns the value of this Long as a float.
Declaration
Following is the declaration for java.lang.Long.floatValue() method
public float floatValue()
Parameters
NA
Return Value
This method returns the numeric value represented by this object after conversion to type float.
Exception
NA
Example 1
The following example shows the usage of Long floatValue() method to get float value from an Long object. We've created a Long variable and assign it a Long object containing a positive long number. Then using floatValue method, we're obtaining the float value from this object and then printed it.
package com.tutorialspoint; public class LongDemo { public static void main(String[] args) { Long obj = new Long(5L); // returns the value of this Long as a float float f = obj.floatValue(); System.out.println("Value of f = " + f); } }
Output
Let us compile and run the above program, this will produce the following result −
Value of f = 5.0
Example 2
The following example shows the usage of Long floatValue() method to get float value from an Long object. We've created a Long variable and assign it a Long object containing a negative long number. Then using floatValue method, we're obtaining the float value from this object and then printed it.
package com.tutorialspoint; public class LongDemo { public static void main(String[] args) { Long obj = new Long(-5L); // returns the value of this Long as a float float f = obj.floatValue(); System.out.println("Value of f = " + f); } }
Output
Let us compile and run the above program, this will produce the following result −
Value of f = -5.0
Example 3
The following example shows the usage of Long floatValue() method to get float value from an Long object. We've created a Long variable and assign it a Long object containing a zero value. Then using floatValue method, we're obtaining the float value from this object and then printed it.
package com.tutorialspoint; public class LongDemo { public static void main(String[] args) { Long obj = new Long(0L); // returns the value of this Long as a float float f = obj.floatValue(); System.out.println("Value of f = " + f); } }
Output
Let us compile and run the above program, this will produce the following result −
Value of f = 0.0
Example 4
The following example shows the usage of Long floatValue() method to get float value from an Long object. We've created a Long variable and assign it a Long object containing a negative zero value. Then using floatValue method, we're obtaining the float value from this object and then printed it.
package com.tutorialspoint; public class LongDemo { public static void main(String[] args) { Long obj = new Long(-0L); // returns the value of this Long as a float float f = obj.floatValue(); System.out.println("Value of f = " + f); } }
Output
Let us compile and run the above program, this will produce the following result −
Value of f = 0.0
