Data.Serialize.IEEE754

Functions for reading, writing and converting IEEE 754 floating point numbers.

Conversions use STUArray and the ST monad to reinterpret bytes and get what we assume to be the IEEE 754 binary representation of single and double precision floating point numbers.

Big-endian reads

getFloat32be :: Get Float

Read a 32-bit float in big endian format

getFloat64be :: Get Double

Read a 64-bit float in big endian format

Little-endian reads

getFloat32le :: Get Float

Read a 32-bit float in little endian format

getFloat64le :: Get Double

Read a 64-bit float in little endian format

Host-endian, unaligned reads

getFloat32host :: Get Float

Read a 32-bit float in native host order and host endianness

getFloat64host :: Get Double

Read a 64-bit float in native host order and host endianness

Little-endian writes

putFloat32le :: Putter Float

Write a 32-bit float in little endian format

putFloat64le :: Putter Double

Write a 64-bit float in little endian format

Big-endian writes

putFloat32be :: Putter Float

Write a 32-bit float in big endian format

putFloat64be :: Putter Double

Write a 64-bit float in big endian format

Host-endian, unaligned writes

putFloat32host :: Putter Float

Write a 32-bit float in native host order and host endianness

putFloat64host :: Putter Double

Write a 64-bit float in native host order and host endianness

Conversions

floatToWord :: Float -> Word32

wordToFloat :: Word32 -> Float

Interpret a 32-bit word as a 32-bit float.

doubleToWord :: Double -> Word64

Interpret a 64-bit float as a 64-bit word.

wordToDouble :: Word64 -> Double

Interpret a 64-bit word as a 64-bit float.
