Java Math copySign Function

May 26, 2023

Java Math Class

Java Math class provides several methods to perform several operations on math calculations like max(), min(), sin(), cos(), round(), ceil(), floor(), copySign() etc.
The java.lang.Math class contains various methods for performing basic numeric operations
Here, in the page we will discuss about the copySign() Method in java.

Java copySign Function :

Java Collection contains Math class and The class Math contains methods for performing several basic and advance numeric operations such as the exponential, logarithm, square root, and trigonometric functions.
The copySign Function takes two arguments, say num1 and num2, and copies the sign of 2nd argument i.e. num2 and assign it to the first argument i.e. num1. It is a static method, so we can call it using math function.

Syntax:

Math.copySign(number1,number2);

Definition of Parameters:

number1 The input or given numbers whose sign is to be replaced.

number2 The input or given numbers whose sign is to be copied.

Return Type :

True : This function returns the 1st argument with the sign of 2nd argument.

clear() Function in ArrayList

clone() Function in ArrayList

add() Function in ArrayList

addall() Function in ArrayList

Example For Double and Float Values:

Run

import java.util.*;

public class Main{
  public static void main(String[] args) {

    // Example of double arguments
    double num1 = 8.65;
    double num2 = -9.40;

    // Example of float arguments
    float num3 = -2.3f;
    float num4 = 4.4f;
    
    // Printing values after performing operation
    System.out.println("Operation on Double : " + Math.copySign(num1, num2));
    System.out.println("Operation on Float : " + Math.copySign(num3, num4));

  }
}

Output:

Operation on Double : -8.65
Operation on Float : 2.3

In the above Example, We had taken two double values and two float values. The copySign Function returns the first argument for both of the values with the sign of their 2nd arguments.

Example for Integer Values:

Run

import java.util.*;

public class Main{
  public static void main(String[] args) {

    // Example of Integer arguments
    int num1 = 8;
    int num2 = -9;

    // Printing values after performing operation
    System.out.println("Operation on Integer Values : " + Math.copySign(num1, num2));
    
    // Printing the data type of output given by copySign Function
    System.out.println("Output is of " + ((Object)Math.copySign(num1, num2)).getClass().getSimpleName() + " Type.");
  }
}

Output:

Operation on Integer Values : -8.0
Output is of Float Type.

In the above Example, We had taken two Integer values. The copySign function returns the floating point value of the 1st argument with the sign of 2nd argument.
