quotient
QUOTIENT num1 num2
(QUOTIENT num)
num1 / num2
outputs the quotient of its inputs. The quotient of two integers
is an integer if and only if the dividend is a multiple of the divisor.
(In other words, QUOTIENT 5 2 is 2.5, not 2, but QUOTIENT 4 2 is
2, not 2.0 -- it does the right thing.) With a single input,
QUOTIENT outputs the reciprocal of the input.
