Hmm, in 8.5, you'll just be able to return NaN. :)

Returning a clearer message is probably better than a simple
division by zero, which is likely to get reported as a bug.
I've got a bunch of such checks in places like modules/math/combinatorics.tcl,
where there are [return -code error] for most of the corner cases.
