i think this makes sense based on the documentation

it depends on whether we consider division by zero an error for floats

if we do, it seems like we should abort the expression entirely, emit an
error message, and return status 2, as we do with 0 / 0. that's the
expected behaviour with an error

if we don't, returning 0 seems correct, since NaN != 0

i don't feel strongly either way but i lean towards not changing it
since it currently works as documented
