data Ratio a

Instances (Integral a, Read a) => Read (Ratio a) (Integral a) => Ord (Ratio a) (Integral a) => Num (Ratio a) (Integral a) => Fractional (Ratio a) (Integral a) => Real (Ratio a) (Integral a) => RealFrac (Ratio a) (Integral a) => Show (Ratio a) (Integral a) => Enum (Ratio a) (Integral a, Eq a) => Eq (Ratio a)

type Rational = Ratio Integer

Arbitrary-precision rational numbers, represented as a ratio of two Integer values. A rational number may be constructed using the % operator.

(%) :: (Integral a) => a -> a -> Ratio a

numerator :: (Integral a) => Ratio a -> a

denominator :: (Integral a) => Ratio a -> a

approxRational :: (RealFrac a) => a -> a -> Rational
