I respect your experience and opinions. To me, trained as a
mathematician, "integer division" is kind of a troublesome notion.
The integers are a commutative ring, not a field. There is no
"division" until we extend the ring to a field by adjoining the
rationals. The function div(x,y) that thinks div(1,2)==0 isn't really
anything I would call "division"; although I understand very well that
this is the traditional thinking in computing.
