Help with java Rounding
Hi, I want to get my Java application to be able to round double varibles, but I do not want to use math.round(), I want to do this another way...

I was thinking of maybe dividing the double variable let say i have

Code:
double z;
then in an if statement dividing the input z by one but only retaning the remainder z%1, the if the remainder is less than .49 print (int)z, or something not sure what way to go here, and if the remainder is greater than .50 then z++. I am still not sure of how to actually set this up.

Thanks

cruxblack will become famous soon enough
U already set up the logic nicely, maybe this how the program would look in its java source code
Code:
import java.util.*; public class Rounder { public static void main(String[] args) { double z; Scanner scan = new Scanner(System.in); z = scan.nextDouble(); if((z%1)>=.50) { z++; } System.out.println((int)z); } }
already tried it, and it works, hope this helps
