class FromInteger a where Source #

fromInteger is special in two ways:

  • numeric integral literals (like "42") are interpreted specifically as "fromInteger (42 :: GHC.Num.Integer)". The prelude version is used as default (or whatever fromInteger is in scope if RebindableSyntax is set).
  • The default rules in haskell2010 specify that constraints on fromInteger need to be in a form C v, where v is a Num or a subclass of Num.

So a type synonym of `type FromInteger a = FromIntegral a Integer` doesn't work well with type defaulting; hence the need for a separate class.

even :: (Eq a, Integral a) => a -> Bool Source #

>>> even 2
True

>>> odd 3
True

(^^) :: (Ord b, Divisive a, Subtractive b, Integral b) => a -> b -> a infixr 8 Source #

raise a number to an Integral power

(^) :: Divisive a => a -> Int -> a infixr 8 Source #

raise a number to an Int power

Note: This differs from (^) found in prelude which is a partial function (it errors on negative integrals). This monomorphic version is provided to help reduce ambiguous type noise in common usages of this sign.
