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.

module Data.Floating.Classes

isInfinite :: RealFloat a => a -> Bool Source

isNaN :: RealFloat a => a -> Bool Source

isNormal :: RealFloat a => a -> Bool Source

isSubNormal :: RealFloat a => a -> Bool Source

isFinite :: RealFloat a => a -> Bool Source

isNegativeZero :: RealFloat a => a -> Bool Source

toFloating :: FloatConvert a b => 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.
