  • 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.StrictMath.abs() method

public static double abs(double a)

Parameters

  • a -- This is the argument whose absolute value is to be determined.

Return Value

This method returns the absolute value of a double value.

Exception

  • NA

Example

The following example shows the usage of java.lang.StrictMath.abs() method.

package com.tutorialspoint;

import java.lang.*;

public class StrictMathDemo {

  public static void main(String[] args) {

    double d1 = 1245.9 , d2 = -987.8;
  
    // returns the absolute value of positive double value
    double dAbsValue = StrictMath.abs(d1); 
    System.out.println("absolute value of " + d1 + " = " + dAbsValue);

    // returns the absolute value of negative double value
    dAbsValue = StrictMath.abs(d2); 
    System.out.println("absolute value of " + d2 + " = " + dAbsValue);
  }
} 

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

absolute value of 1245.9 = 1245.9
absolute value of -987.8 = 987.8
