data Double Source

The Double type. This is expected to be an identical declaration to the one found in GHC.Prim. We avoid simply using GHC's type because we need to define our own class instances. Constructors D# Double# Instances Enum Double Eq Double Fractional Double Num Double Read Double Show Double Sortable Double Poset Double RealFloat Double Floating Double Roundable Double FloatConvert Integer Double Real a => FloatConvert a Double FloatConvert CDouble Double FloatConvert Float Double FloatConvert Double CDouble FloatConvert Double Float

data Float Source

class FloatConvert a b where Source

Coercion to floating point types. Methods toFloating :: a -> b Source Convert to a floating point type. Conversions from integers and real types are provided, as well as conversions between floating point types. Conversions between floating point types preserve infinities, negative zeros and NaNs.
