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].
