data Ratio a

Instances Typeable a => Typeable (Ratio a) (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
