The \ operator (also called the remainder
operator) calculates the remainder of dividing the `dividend` by the `divisor` (otherwise known as the modulo).

dividend\divisor

There is no limitation on the
numeric value of the `dividend` or `divisor`.

In this example, 5 (the remainder of 21/8) is printed.

x = 21 y = 8 z = x \ y print z
