Does .999~=1?

**a12ctic** · 11-02-2005

ok, this comes straight from another forum, and has about a 10 page disscusion, what you guys think

i think that it doesnt, because .999~ will never get to be 1

i agree...it doesn't equal 1, but it's often rounded to 1 to make things simpler...and sometimes more efficient (easier to write...)

Yes it does. See Zeno's Paradoxes

I've had this discussion before on another forum. Basically, because of some weird Calculus thing, it actually does equal 1.

Blizzard has a press release on it after a huge debate on their forums:

Look at the date of that article.

I would have originally said no but this seems to have some solid mathematical backing and I don't even like math.

Seriously though, it is just normal calculus.

That proof is invalid (I think

). It only appears valid because people find it hard to imagine the endless number of 9's after the decimal point and so make computational errors when they try to think about it. This is a common problem that arises when trying to think about infinities. For example, infinity minus infinity is not zero -- mathematicians would call it "undefined". Similary with zero divided by zero.

0.999999...... is not 1. It's just as close as you can get without actually being 1.

I think.....
