An interesting question you pose, but anything divided by 0, will always be undefined, not infinity, even if you are using terms over zero, it will still be undefined.
Dante224 has also covered this,
I would like to point out however, it is undecided that 0/0 is undefined, or equals 1, like bdunwithat stated, for it has the potential to be both. (anything divided by itself will always equal 1, and the divide by zero law interfere here).
lol good music, from castle crashers of course.
