Java - Math abs(double) method
Description
The Java Math abs(double a) returns the absolute value of a double value. If the argument is not negative, the argument is returned. If the argument is negative, the negation of the argument is returned.Special cases −
- If the argument is positive zero or negative zero, the result is positive zero.
- If the argument is infinite, the result is positive infinity.
- If the argument is NaN, the result is NaN.
Declaration
Following is the declaration for java.lang.Math.abs() method
public static double abs(double 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
Example 1
The following example shows the usage of Math abs() method to get absolute value of a positive double value.
package com.tutorialspoint; import java.lang.Math; public class MathDemo { public static void main(String[] args) { // get a double to find its absolute values double x = 4876.1874d; // 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(4876.1874)=4876.1874
Example 2
The following example shows the usage of Math abs() method to get absolute value of a zero double value.
package com.tutorialspoint; import java.lang.Math; public class MathDemo { public static void main(String[] args) { // get a double to find its absolute values double x = -0.0d; // 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)=0.0
Example 3
The following example shows the usage of Math abs() method to get absolute value of a negative double value.
package com.tutorialspoint; import java.lang.Math; public class MathDemo { public static void main(String[] args) { // get a double to find its absolute values double x = -9999.555d; // 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(-9999.555)=9999.555
