casting an int

[droidus]

I am trying to take numbers in as an int, then put out the decimal value. for example, 1/2 = 1.2. here is my code:

      Scanner console = new Scanner(System.in);
		System.out.print("numerator: ");
      int numerator = console.nextInt();

		System.out.print("denominator: ");
      int denominator = console.nextInt();
		
		double fraction = (double) (numerator/denominator);

Only problem is, i get 0. am i casting wrong?

It's a matter of order. With your parenthesis as they are: (double) (numerator/denominator), you first do int division which always returns an int (here zero), and then change it to a double. Instead place the cast inside the parenthesis:

double fraction = ((double) numerator/denominator);

In fact there's no need for the outer parenthesis at all:

double fraction = (double) numerator/denominator;
