Question

I’m making this program for a class and I need to guess a number’s cube root. Here’s my code:

int N = Integer.parseInt(args[0]);

//sets the guess at 1.0
guess = 1.0;

//whether or not the guess is close to N
while (guess * guess * guess <= N ){

     double show = (guess + ((1/3) * ((N / (guess * guess)) - guess)));
     System.out.println(show);
     guess = show;
     continue;

}

However, every time I run this program, the double show is always set to the value 1. Can anyone please tell me why this is happening and how I can fix it?

Answer 1

1/3 = 0

because 1/3 is integer division and that is always 0. It should be

1.0/3.0
