How can I divide without flooring in Java?

Question

I'm trying to divide an integer by an integer in Java and return a long result. I tried the following, but I keep getting "0".

System.out.println(Long.valueOf(5) / Long.valueOf(18));
System.out.println((long)5 / (long)18);

Answer 1

You don't need a long, you need a double.

System.out.println(5 / 18.0);

or

System.out.println(5.0 / 18);

Of course this will work too:

System.out.println(5.0 / 18.0);

Answer 2

It seems everyone has given the right answer, but you should note you can also do

System.out.println(5 / 18f)

Where f makes it a float

System.out.println(5 / 18d)

where d makes it a double

Answer 3

Long is for "long" integer numbers. You should use float or double instead.
