That's useful to know - thanks Florian. So it's possible to forego the
-1 check if no downsizing occurs.
I suppose it makes sense... if we go by the signed 64-bit equivalents,
$8000 div $ = $8000, which when
typecast to a LongInt does result in a
So I need to ask... should the check for a divisor of -1 still be
performed? The case of doing "min_int div -1", even with
unsigned-to-signed typecasting, seems very contrived and the programmer
should expect problems if "min_int" and "-1" appear as the operands. Is
there a specific example

Yes. This is the result of "down sizing" a division. In case of
longint(int64 div int64) can be converted only into longint(int64) div
longint(int64) if
