button.setOnClickListener(new View.OnClickListener() {

            int weight_position=spinner_weight.getSelectedItemPosition();
            int height_position=spinner_height.getSelectedItemPosition();

            double converted_height=height_position/100;
            double doubleHeight=converted_height*converted_height;
            double body_mass_index= weight_position/doubleHeight;
            Toast.makeText(getApplicationContext(), "result is: "+body_mass_index, Toast.LENGTH_LONG).show();

Hello, I was trying to develop a simple ideal weight calculator via spinners. First spinner for weight (kg) Second spinner for height (cm) Output(toast message) is; "result is Infinity"

`doubleHeight` is zero, `weight_position` is positive. – Andy Turner Apr 26 '17 at 14:59
Thanks but I can't get it clearly. Can you be little more specific? – user3469764 Apr 26 '17 at 15:11
Use `height_position/100.0` instead. `height_position < 100`, it would appear, so `height_position/100 == 0`. – Andy Turner Apr 26 '17 at 15:14
