% Operator

% calculates the remainder when dividing the first number by the second number.

6 % 3 //-> 0
7 % 3 //-> 1

As with division, % 0 will throw an exception.

6 % 0 //-> *exception*

% also works with negative numbers, using the Euclidean remainder.

When the first operand is negative, the result is the difference from the next smallest multiple.

// From -4, the next smallest multiple of 3
// is -6, and -4 is 2 greater than -6.
-4 % 3 //-> 2
