Output of the program :
package com.hubberspot.code; public class SignumDemo { public static void main(String[] args) { // Creating three ints variable holding // a negative integer, a positive integer // and 0 integer. int zero = 0; int positive = 10; int negative = -20; // Signum function calculates and returns following : // for zero value it returns 0.0 // for positive value it returns 1.0 // for negative value it returns -1.0 double zeroSign = Math.signum(zero); double positiveSign = Math.signum(positive); double negativeSign = Math.signum(negative); // printing the values of signum function of integers System.out.println("Signum of " + zero + " is " + zeroSign); System.out.println("Signum of " + negative + " is " + negativeSign); System.out.println("Signum of " + positive + " is " + positiveSign); } }
