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() methodimport 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
