Euclidean modulo operator.
Returns the remainder of the euclidean division. The euclidean division of
two integers a and b yields two integers q and r such that
a == b * q + r and 0 <= r < b.abs().
The euclidean division is only defined for integers, but can be easily
extended to work with doubles. In that case r may have a non-integer
value, but it still verifies 0 <= r < |b|.
The sign of the returned value r is always positive.
See remainder for the remainder of the truncating division.
