Dunno if this has already been covered, if so, sorry for the spam, not intended.
So:

Let's call .99999~ (that's a decimal followed by an infinite number of 9's) a variable x.

So that means that x = .9999~

So by that logic, 10x = 9.9999~

If you subtract x from 10x, you get 9.00000~, as in the equation 10x - x = 9.00000~

This means 9.0000~, or just 9 (I put the 0's there to show that all the 9's after decimal went away), equals 9x.
9x = 9

Divide each side by 9, and you get x = 1.

That means that x is equal to .99999~ and 1 at the same time. Therefore, .99999~ = 1!

There is also another (less complicated) way to find that 0.99999~ = 1.

1/3 = 0.33333~

3 * 1/3 = 3/3 = 1

So,

3 * 0.33333~ = 0.99999~ = 1!

This post looks kinda nerdy but it shocked me to see that 0.99999~ =1 lol

By the way, everyone has A) Seen it before, and not cared, or B) Never seen it before, and doesn't care.

Hmm, interesting. For general things like money, $0.99 is $1 for me anyways.

You bring up a good thing, if only stores would just stop doing the 99 cent thing. If it's one dollar, make it one dollar, I don't want 99 cents.

The 0,99 cent thing is more of a psychological thing. Studies have been done on whether or not people bought more of an item that was "€19,99" or "€20,00" and they prefer the €19,99. *shrug*

That's because it seems less.

Anyway. The more 9s there are the closer to one it gets. It is more sensible to round it up since you don't need so many dps.

yeah i mean after the first 10000 9's you would probably just go "man make it equal to 1"

It also allows shop to say "<item here> - less than £100!" when they're selling it at £99.99.

well i was watching a special on shopping. they did 2 test, they were selling canned soup for .99 no limit. people bought only 1-2 and that was it. then a few hours later they put up "limit of 5 per person" and everybody that went by bought all 5.

also if you shop with a list you're more likely to be spending more because after you have everything on the list you tend to "hey i deserve something for myself"
