Title: Dividing by zero
Post by: cosmic_c on September 20, 2010, 08:56:39 PM
You have noticed, or didn't care, I've been gone for a while. Well for my last math test I had problem no. 78. "What is (8X4)-3/0?" Well I guess it was actually a glitch in printing. Most people skipped the question while I tried to solve it. That was a bad idea. The page then split into two and in the center was a blue and black vortex that flung me a couple of weeks into the future. So......

So if were to divide by zero, or if you have, what would (or did) happen to you?

You should have just used a calculator you big dummy. The answer is obviously - E -

I get +∞ or -∞, end of story.  Unless the problem involves 0/0, then I gotta apply some L'Hôpital's Rule or other fancy limitwork.  Why this "dividing by 0 = doomsday" stuff ever got started I can't imagine.

Most computers hurt themselves when they try to calculate infinity.

Fine, if we're going to take this seriously you don't "get ∞", you get "undefined". Problem no. 78 was just simplifying an expression; there are no limits.

Wait, when did the problem become about Batman?

This is what happens when an unstoppable force meets an immovable object.

Dividing by zero is more an inconvenience (or frustration) to me because whatever calculation or program I was working on comes to a screeching halt. Give me an opportunity to change the last thing I put in, but don't suddenly screw up the whole result just because of an error on my part. Changing the result to NaN (not a number) isn't much better. The idea of "nullity" or whatever it is that supposedly has an answer to dividing by zero sounds more like a way for systems to continue working when that happens (just so they don't have to handle it themselves), and yet you'll still be locked into a predetermined answer (in this case, nullity) that will probably screw up the rest of your calculation.

As for why dividing by zero leads to death and destruction... well, some systems have failed before because dividing by zero made them crash and they neglected to check for that. If the universe divided by zero and forgot to check for that, then you'd probably see the destruction they're talking about. Even if the destruction is usually a black hole.

It's simple: Kill the zero.

If you divide by zero, that means you are splitting something up into zero equal parts. If you have zero parts, that means that you have zero! Whenever you divide by zero you get zero, just like when you divide by one you just get the original number again.

you are splitting something up into zero equal parts.
But have you ever tried splitting something into 0 parts?
