Java.lang.StrictMath.copySign() Method

---

Description

The java.lang.StrictMath.copySign(double magnitude, double sign) method returns the first floating-point argument with the sign of the second floating-point argument. For this method, a NaN sign argument is always treated as if it were positive.

Declaration

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

public static double copySign(double magnitude, double sign)

Parameters

• magnitude − This is the parameter providing the magnitude of the result

• sign − This is the parameter providing the sign of the result

Return Value

This method returns a value with magnitude and sign.

Exception

NA

Example

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

package com.tutorialspoint;

import java.lang.*;

public class StrictMathDemo {

   public static void main(String[] args) {

      double d1 = 3.8 , d2 = -1, d3 = 1 , d4 = -14;
   
      /* returns the first double argument with the sign of the
         second double argument */

      double signedValue = StrictMath.copySign(d1, d2); 
      System.out.println("value of d1 with sign d2 : " + signedValue);

      signedValue = StrictMath.copySign(d1, d3);
      System.out.println("value of d1 with sign d3 : " + signedValue);

      signedValue = StrictMath.copySign(d2, d4);
      System.out.println("value of d2 with sign d4 : " + signedValue);
   }
}

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

value of d1 with sign d2 : -3.8
value of d1 with sign d3 : 3.8
value of d2 with sign d4 : -1.0
