Unexpected output in dividing two numbers

Question

Why is this code giving 0.0 as answer?

public static void main(String[] args) {
    float ans = (480/1080);
    System.out.println(ans);
}

Answer 1

You are dividing two integers, so the result is integer. 480/1000 < 1 and is therefore truncated to 0. Then the result is cast to float to be stored in the float variable.

To divide the numbers as floats, cast one of them:

float ans = ((float)480/1080);

Answer 2

Try this.. Here both numbers will be float so You'll get float value..

 float ans = ((float)480/(float)1080);
            System.out.println(ans);

Output:
0.44444445
