Char arithmetic

Question

Can anyone please explain to me what's happening here😨

public class Program
{
public static void main(String[] args) {
char ch = '0';

ch *= 1.1;

System.out.println(ch);

}
}

Output:
4

Answer 1

The ASCII value of '0' is 48.

48 * 1.1 = 52.8

52.8 floored (52) and reinterpreted to char is is '4'.
