Java.lang.StrictMath.abs() Method



The java.lang.StrictMath.abs(float a) method returns the absolute value of a float value. If the argument is not negative, the argument is returned. If the argument is negative, the negation of the argument is returned. It includes some 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.


Following is the declaration for java.lang.StrictMath.abs() method

public static float abs(float a)


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

Return Value

This method returns the absolute value of a float value.




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) {

      float f1 = 78 , f2 = -9;
      // returns the absolute value of positive float value
      float fAbsValue = StrictMath.abs(f1);
      System.out.println("absolute value of " + f1 + " = " + fAbsValue);
      // returns the absolute value of negative float value
      fAbsValue = StrictMath.abs(f2);
      System.out.println("absolute value of " + f2 + " = " + fAbsValue);

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

absolute value of 78.0 = 78.0
absolute value of -9.0 = 9.0
