Java - Dividing two integers gives 0?

Question

I might be missing something simple here, but when I divide two numbers that definately should not equal 0, I'm getting 0.

I've tried forcefully casting the values. SongDuration, originalSongDuration are integers. I need the percentage to be a float.

System.out.print("SongDuration: " + songDuration + " :: originalSongDuration: " + originalSongDuration + " :: percentage: " + (float) ((int)songDuration / (int)originalSongDuration));

[17:43:03 INFO]: SongDuration: 64746 :: originalSongDuration: 140746 :: percentage: 0.0

Thanks.

(float) ((float)songDuration / (float)originalSongDuration));

If you want a percent you should use floats. Diving one int by another will never give a decimal value. You are probably getting 0 returned because of this property of ints

FYI you don't need to cast both vars to float, just one will suffice. And as long as the variable where you're storing the result is a float, you don't need to cast the result. An alternative would be to multiply one of the vars by 1.0 – mstbaum Jun 10 '15 at 21:48
