Program: Example for Math.signum() method.


Math.signum() function returns zero if the passed argument is zero, 1.0 if the passed argument is greater than zero, -1.0 if the passed argument is less than zero.

package com.java2novice.math;

public class MySignumEx {

	public static void main(String a[]){
		System.out.println("signum value of 20.23 is: "+Math.signum(20.23));
		System.out.println("signum value of 0 is: "+Math.signum(0));
		System.out.println("signum value of -20.23 is: "+Math.signum(-20.23));

signum value of 20.23 is: 1.0
signum value of 0 is: 0.0
signum value of -20.23 is: -1.0
