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
