ByteOrdering

ByteOrdering

is an option for BinaryRead, BinaryWrite, and related functions that specifies what ordering of bytes should be assumed for your computer system.

Details

  • Possible settings for ByteOrdering are +1 and -1.
  • +1 corresponds to big endian (appropriate for PowerPC 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].
