round up/round down?

Question

i got to this question which asks for the value of the variable result:
int x = 15; int y = 4;
int result = x / y;
System.out.println(result);
15 divided by 4 is 3.75 and i understand that because the variable result is an integer the answer will be a single figure as an integer is a whole number, what i don't understand is why is the answer rounded down to 3 instead of rounded up to 4? can someone shed some light please?

Answer 1

A good way to round down is Math.floor() it goes like this in your case.

import java.lang.Math; //Make sure you put this on top of everything
int x=15; int y =4;
int result = x/y;
double result2 = Math.floor(result);
System.out.println(result2);

Hope this helps!
