The java.lang.Math.copySign() method returns the first argument with the sign of the second argument.

Note:
Arguments can be of two types:

  • double type : copySign(double magt, double sign)
  • float type : copySign(float magt, float sign)

Syntax :

public static double copySign(DataType magt, DataType sign)
Parameter :
 magt: argument providing the magnitude of the result.
 sign : argument providing the sign of the result.
Return :
This method returns the magnitude of the first argument with the sign of the 
second argument.

Example :To show working of java.lang.Math.copySign() method.




// Java program to demonstrate working
// of java.lang.Math.copySign() method
import java.lang.Math;
  
class Gfg {
  
    // driver code
    public static void main(String args[])
    {
        double a = 34.543;
        double b = -123.44;
  
        // Input a, b
        // Output -34.543( a- Magnitude, b- Sign)
        System.out.println(Math.copySign(a, b));
  
        // Input b, a
        // Output 123.44( b- Magnitude, a- Sign)
        System.out.println(Math.copySign(b, a));
  
        float c = 87.56f;
        float d = -685.23f;
  
        // Input c, d
        // Output -87.56( c- Magnitude, d- Sign)
        System.out.println(Math.copySign(c, d));
  
        // Input d, c
        // Output 685.23( d- Magnitude, c- Sign)
        System.out.println(Math.copySign(d, c));
    }
}


Output:

-34.543
123.44
-87.56
685.23
