Java - Math abs(long) Method
Description
The Java Math abs(long a) returns the absolute value of a long value. If the argument is not negative, the argument is returned. If the argument is negative, the negation of the argument is returned. Note that if the argument is equal to the value of Long.MIN_VALUE, the most negative representable long value, the result is that same value, which is negative.
Declaration
Following is the declaration for java.lang.Math.abs() method
public static long abs(long a)
Parameters
a − the argument whose absolute value is to be determined
Return Value
This method returns the absolute value of the argument.
Exception
NA
Getting Absolute Value of Positive Long Value Example
The following example shows the usage of Math abs() method to get absolute value of a positive long value.
package com.tutorialspoint; public class MathDemo { public static void main(String[] args) { // get a long to find its absolute values long x = 4876L; // get and print its absolute value System.out.println("Math.abs(" + x + ")=" + Math.abs(x)); } }
Output
Let us compile and run the above program, this will produce the following result −
Math.abs(4876)=4876
Getting Absolute Value of Zero Long Value Example
The following example shows the usage of Math abs() method to get absolute value of a zero long value.
package com.tutorialspoint; public class MathDemo { public static void main(String[] args) { // get a long to find its absolute values long x = -0L; // get and print its absolute value System.out.println("Math.abs(" + x + ")=" + Math.abs(x)); } }
Output
Let us compile and run the above program, this will produce the following result −
Math.abs(0)=0
Getting Absolute Value of Negative Long Value Example
The following example shows the usage of Math abs() method to get absolute value of a negative long value.
package com.tutorialspoint; public class MathDemo { public static void main(String[] args) { // get a long to find its absolute values long x = -9999L; // get and print its absolute value System.out.println("Math.abs(" + x + ")=" + Math.abs(x)); } }
Output
Let us compile and run the above program, this will produce the following result −
Math.abs(-9999)=9999
