parseFloatBE :: RealFloat a => [Word8] -> a

Parse a big-endian byte list into a floating-point value.

parseFloatLE :: RealFloat a => [Word8] -> a

Parse a little-endian byte list into a floating-point value.

getFloat16be :: Get Float

getFloat16le :: Get Float

getFloat32be :: Get Float

getFloat32le :: Get Float

getFloat64be :: Get Double

getFloat64le :: Get Double

getFloat :: RealFloat a => BitCount -> ([Word8] -> a) -> Get a

Parse a floating-point value of the given width from within a Get monad.

exponentWidth :: BitCount -> BitCount

Calculate the proper size of the exponent field, in bits, given the size of the full structure.

bitSlice :: [Word8] -> BitCount -> BitCount -> Integer

Considering a byte list as a sequence of bits, slice it from start inclusive to end exclusive, and return the resulting bit sequence as an integer

splitRawIEEE754 :: [Word8] -> (Bool, Exponent, Fraction)

Split a raw bit array into (sign, exponent, fraction) components. These components have not been processed (unbiased, added significant bit, etc).

unbias :: Exponent -> BitCount -> Exponent

Unbias an exponent

mergeFloat :: Exponent -> Fraction -> BitCount -> (Integer, Int)

Parse values into a form suitable for encodeFloat sign exponent fraction width-in-bits -> fraction, exponent

type Exponent = Int

type Fraction = Integer

type BitCount = Int
