Bool#
Int#
intEncodeDouble# :: Int# -> Int# -> Double# Source #

(provided by GHC's RTS)
Word#
quotRemWord3# :: (# Word#, Word# #) -> Word# -> (# (# Word#, Word# #), Word# #) Source #
2-by-1 large division
Requires: b0 /= 0 a1 >= b0 (not required, but if not q1=0)

The endianness is selected with the Bool# parameter: write most significant
byte first (big-endian) if 1# or least significant byte first
(little-endian) if 0#.
wordFromAddrLE# :: Word# -> Addr# -> State# s -> (# State# s, Word# #) Source #
Read a Word from addr in base-256 little-endian representation.
@n is the number of bytes to read.
wordFromAddrBE# :: Word# -> Addr# -> State# s -> (# State# s, Word# #) Source #
Read a Word from addr in base-256 big-endian representation.
@n is the number of bytes to read.
wordToAddr# :: Word# -> Addr# -> Bool# -> State# s -> (# State# s, Word# #) Source #
Write a Word to addr in base-256 representation and
return the number of bytes written.
The endianness is selected with the Bool# parameter: write most significant
byte first (big-endian) if 1# or least significant byte first
(little-endian) if 0#.
wordToAddrLE# :: Word# -> Addr# -> State# s -> (# State# s, Word# #) Source #
Write a Word to addr in base-256 little-endian representation and
return the number of bytes written.
wordToAddrBE# :: Word# -> Addr# -> State# s -> (# State# s, Word# #) Source #
Write a Word to addr in base-256 big-endian representation and
return the number of bytes written.
wordWriteAddrLE# :: Word# -> Addr# -> State# s -> State# s Source #
Write a full word with little-endian encoding
wordWriteAddrBE# :: Word# -> Addr# -> State# s -> State# s Source #
Write a full word with little-endian encoding
ByteArray import/export
wordFromByteArray# :: Word# -> ByteArray# -> Word# -> Bool# -> Word# Source #
Read a Word from ByteArray in base-256 representation.
@n is the number of bytes to read.
The endianness is selected with the Bool# parameter: write most significant
byte first (big-endian) if 1# or least significant byte first
(little-endian) if 0#.
wordFromByteArrayLE# :: Word# -> ByteArray# -> Word# -> Word# Source #
Read a Word from ByteArray in base-256 little-endian representation.
@n is the number of bytes to read.
wordFromByteArrayBE# :: Word# -> ByteArray# -> Word# -> Word# Source #
Read a Word from ByteArray in base-256 big-endian representation.
@n is the number of bytes to read.
wordToMutableByteArray# :: Word# -> MutableByteArray# s -> Word# -> Bool# -> State# s -> (# State# s, Word# #) Source #
Write a Word to MutableByteArray in base-256 representation and
return the number of bytes written.
The endianness is selected with the Bool# parameter: write most significant
byte first (big-endian) if 1# or least significant byte first
(little-endian) if 0#.
The offset is in bytes.
wordToMutableByteArrayLE# :: Word# -> MutableByteArray# s -> Word# -> State# s -> (# State# s, Word# #) Source #
