Description
Returns the top half of a fraction expressed as a/b. The fraction is automatically converted to the canonical reduced form, that is, both the numerator and denominator are divided by their highest common divisor, if one exists. 2/4 , for example, would be converted to 1/2 before the denominator is dropped. numerator of an integer returns the integer itself.
