Neither is a mathematical operator as far as mathematicians are concerned, and
we also don't set all operators upright -- only certain ones.
The convention you mention is one adopted by some physicists, engineers, and
other users of "applied" mathematics for reasons with which most (if not all)
"pure" mathematicians either just do not agree or regard as plain wrong.
