    % = modulus

    it will take the remainder of two ints.
    example

    12%7 = 5

    (7 goes into 12 once , and there is a remainder 5 )

    20%4 = 0

    (4 goes into 20 five times, and there is no remainder )

    1%3 = 1

    (3 goes into 1 zero times, and there is 1 remainder )

    hope that helps
    there are only 10 people in the world, those who know binary and those who dont

    The % operator is the modulus, the / operatoris is the divisor and it is applicable to integer variables. It has to do with the remainder of a division.

    In integer calculus you get the following:

    7 / 3 = 2

    Now

    2 * 3 = 6

    So there is a remainder

    7 - 6 = 1

    This can directly be calculated using the modulus operator

    7 % 3 = 1

    In your example

    1 / 3 = 0
    0 * 3 = 0
    1 - 0 = 1
