java - Unexpected output in dividing two numbers -

-

this question has answer here:

why code giving 0.0 answer?

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

you dividing 2 integers, result integer. 480/1000 < 1 , therefore truncated 0. result cast float stored in float variable.

to divide numbers floats, cast 1 of them:

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