Marick, I will smack you.
How can you even have a 1 at the END of an "infinite amount of zeroes?" That's a contradiction. If the zeroes are infinite, there is no end.the only number that can be between .999... and 1 is .00...01 where there are an infinite amount of zeroes.
1. It's "for all intents and purposes.".999... for all intensive purposes has no mathematical difference to 1
2. Not only is it true for all intents and purposes, it doesn't even need that qualification. It's EXACTLY equal.
EDIT: haha, I thought you'd edited your post but I realized it was on the end of my last page that I had missed earlier.
EDIT 2:Only one of those is right (undefined). And undefined does not equate to infinity, it means just what it says: undefined.According to Arithmetic: 0/0 = 1, 0, undefined (infinity) too...
