- afromRational :: HasCallStack => Rational -> a
Documentation
class FromRational a where Source #
Replaces base's fromRational functionality for when we do not have a
Fractional instance.
5.5 :: Fractional a => a -- becomes afromRational 5.5 :: FromRational a => a
Note that fromRational's deficiencies are inherited e.g. Natural is
partial, bounded types have over/underflow issues.
