= M =
Not big-endian or
little-endian. Used of perverse byte orders such as 3-4-1-2
or 2-1-4-3, occasionally found in the packed-decimal formats of
minicomputer manufacturers who shall remain nameless. See NUXI problem. Non-US hackers use this term to describe the American
mm/dd/yy style of writing dates (Europeans write little-endian
dd/mm/yy, and Japanese use big-endian yy/mm/dd for Western dates).
