Copy sign

static double copySign(double magnitude, double s): Returns the first floating-point argument with the sign of s.
static float copySign(float magnitude, float s): Returns the first floating-point argument with the sign of s.


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

    System.out.println(Math.copySign(2.2,3.3));
    System.out.println(Math.copySign(2.2,-3.3));
  }
}

The output:


2.2
-2.2
