</div>% is the remainder operator:<br>

<br>
it is how much remains after you perform an integer division, e.g. 23<br>
% 5 == 3, since 20 / 5 == 4 and then you are left with 3.<br>
<br>
n % y == 0 if n is divisible by y. This is useful in factoring prime<br>
numbers, and in the case of y == 2, for checking if the number n is<br>
even.<br>
