The proper response to a question like that is "what business
is it of yours?". Maybe he's passing the column to some verb that
he got from somebody else. He just wants reliable, predictable
behavior of empties. There shouldn't have to be any discussion
of motive.
But in case he didn't get the verb from somebody else:
{.!.0
works to coerce an empty to numeric type.
