Arbitrary-precision rational numbers, represented as a ratio of two Integer values. A rational number may be constructed using the % operator.
numerator :: Integral a => Ratio a -> aSource
Extract the numerator of the ratio in reduced form: the numerator and denominator have no common factor and the denominator is positive.
denominator :: Integral a => Ratio a -> aSource
Extract the denominator of the ratio in reduced form: the numerator and denominator have no common factor and the denominator is positive.
