Standard functions on rational numbers

Synopsis

data Ratio a
(%) :: Integral a => Exp a -> Exp a -> Exp (Ratio a)
pattern (:%) :: Elt a => Exp a -> Exp a -> Exp (Ratio a)
numerator :: Exp (Ratio a) -> Elt a -> Exp a
denominator :: Exp (Ratio a) -> Elt a -> Exp a

Documentation

data Ratio a #

Rational numbers, with numerator and denominator of some Integral type.

Note that Ratio's instances inherit the deficiencies from the type parameter's. For example, Ratio Natural's Num instance has similar problems to Natural's.
