IEEE floating-point special values

GHC.Real defines infinity and notANumber as Rational. We export variants which are polymorphic because that can be more helpful at times.

infinity :: Fractional a => a Source

negativeInfinity :: Fractional a => a Source

notANumber :: Fractional a => a Source

Basic functions

log :: Floating a => a -> a Source

toFractional :: (Real a, Fractional b) => a -> b Source

LogFloat data type and conversion functions

data LogFloat Source

Instances Eq LogFloat Fractional LogFloat Num LogFloat Ord LogFloat Real LogFloat Show LogFloat

logFloat :: Real a => a -> LogFloat Source

logToLogFloat :: Real a => a -> LogFloat Source

fromLogFloat :: Floating a => LogFloat -> a Source

logFromLogFloat :: Floating a => LogFloat -> a Source
