Fit.Internal.Numbers

Little-endian and big-endian parsers for signed and unsigned integers, and for single-precision and double-precision floating point numbers.

The parsers are tagged for endianness using the tools in Fit.Internal.Architecture.

Little-endian parsers

int16le :: LittleEndian (Parser Int16)

int32le :: LittleEndian (Parser Int32)

int64le :: LittleEndian (Parser Int64)

word16le :: LittleEndian (Parser Word16)

word32le :: LittleEndian (Parser Word32)

word64le :: LittleEndian (Parser Word64)

float32le :: LittleEndian (Parser Float)

float64le :: LittleEndian (Parser Double)

Big-endian parsers

int16be :: BigEndian (Parser Int16)

int32be :: BigEndian (Parser Int32)

int64be :: BigEndian (Parser Int64)

word16be :: BigEndian (Parser Word16)

word32be :: BigEndian (Parser Word32)

word64be :: BigEndian (Parser Word64)

float32be :: BigEndian (Parser Float)

float64be :: BigEndian (Parser Double)

Helpers

nByteIntLe :: (Integral a, Bits a) => Int -> Parser a

Parse n bytes and interpret them as a little-endian integer. The caller must ensure that the returned type is the correct size for the number of bytes parsed.

nByteIntBe :: (Integral a, Bits a) => Int -> Parser a

Parse n bytes and interpret them as a big-endian integer. The caller must ensure that the returned type is the correct size for the number of bytes parsed.
