No, I don't suppose there is, but we'd need a pretty convincing
argument.  At the time of ANS Forth almost no-one knew about Euclidan
division, and I'm still not convinced there's much of a case for it.
Forth, Inc practice was to treat all MOD operations as unsigned, and
that still seems pretty sensible to me.  Truncated division is
inferior to the others, but people still use it for the sake of a few
cycles, so I guess in most cases people don't care.

Andrew.
