Description

Ratios of mathematical objects.

Synopsis

data T a = (:%) { numerator :: !a denominator :: !a } (%) :: C a => a -> a -> T a type Rational = T Integer fromValue :: C a => a -> T a scale :: C a => a -> T a -> T a split :: C a => T a -> (a, T a) showsPrecAuto :: (Eq a, C a, Show a) => Int -> T a -> String -> String

data T a

Constructors (:%) numerator :: !a denominator :: !a Instances (Arbitrary a, C a, C a) => Arbitrary (T a) C a => C (T a) C a => C (T a) (Ord a, C a) => C (T a) (C a, C a) => C (T a) C a => C (T a) (Ord a, C a) => C (T a) C a => Divisible (T a) Eq a => Eq (T a) (Num a, C a) => Fractional (T a) (Num a, C a) => Num (T a) (Ord a, C a) => Ord (T a) (Read a, C a) => Read (T a) (Real a, C a) => Real (T a) (ToInteger a, C a) => RealFrac (T a) (Show a, C a) => Show (T a) (ToInteger a, C a) => ToRational (T a)

(%) :: C a => a -> a -> T a

type Rational = T Integer

fromValue :: C a => a -> T a

scale :: C a => a -> T a -> T a

split :: C a => T a -> (a, T a)

similar to splitFraction

showsPrecAuto :: (Eq a, C a, Show a) => Int -> T a -> String -> String

This is an alternative show method that is more user-friendly but also potentially more ambigious.
