$ByteOrdering

$ByteOrdering

gives the native ordering of bytes in binary data on your computer system.

Details

  • Possible values of $ByteOrdering are +1 and -1.
  • +1 corresponds to big endian (appropriate for 680x0 and many other processors); -1 corresponds to little endian (appropriate for x86 processors).
  • +1 corresponds to having the most significant byte first; -1 to having the least significant byte first.
  • +1 is the order obtained from IntegerDigits[n,256].
  • $ByteOrdering gives the default setting for the ByteOrdering option in Import and Export.
