Therefore


The difference between 1 and .99999 Repeating is 1/infinity or 0

Therefore 1 = .99999 Repeating


CLIFFS
--------------
1-.9 = .1
1 - .99 = .01
1- .999 = .001
1 - .9999 Repeating = 0

it only equals zero for people too lazy to write out the whole number :|

It wouldn't be zero, it'd just be an exponentially small fraction.

You're saying 1/infinity isn't zero?

lim x -> infinity of 1/10^x != 0?

The difference between 1 and .99999 Repeating is 1/infinity or 0

Therefore 1 = .99999 Repeating

By the same logic, the difference .9999999~8 and .9999999~ is 1/infinity = 0 therefore it's the same as .9999~ which is the same as 1, ditto for .9999999~7 and .9999999~6 and .9999999~5 and so forth, which thus all equal 1. Congratulations, you've just made the concept of numbers irrelevant.

What the heck is .9999~8?

You're wrong. It's not philosophy, it's math. 1 = .999... and that is that.


This thread ends *now*

In logic, 1 = 1, and .999... would not equal 1. Since .9999... is a different number than 1, it cannot be 1.


An infinite number of 9's following the decimal point means that in each digit, the "9" indicates that it falls short of "10". It is infinite 9's.... there is no 10. It misses 1 by an infinitely small number, which is math is not significant. But in logic, it is significant.

your logic is flawed because you do not take into account the meaning of infinity.

What's the point in saying you're wrong because of x, without explaining x?

No one - NO ONE - has provided even the slightest proof as to why .9999.... does not equal one. Meanwhile, those that contend that .99999 = 1 have provided at least a rough proof indicating why.

A logical person would believe the latter.

Edit, for what it's worth, glenn1 is a fricking moron. .9999~8 or whatever, is not equal to .99999..... .9999999.... cannot be represented as anything other noninteger number other than .9999999....

Him trying to do so invalidates the concept of numbers - not the 'proof' (if you can call it that) that he claims to present. Congratulations, he just failed 8th grade math.

Actually I think it's the other way around. Just because some guy teaching a math class says it's true doesn't mean it is. Any logical person would look at it and say you are crazy. 1 = 1, .99R = .99R, no two different things equal each other.

it's what the village idiot that doesn't understand the concept of infinity writes.

PSA: if you haven't gotten that 0.9999...=1 yet you are officially a dumbass. Mods should lock and sticky that statement at the top of off topic and lock all bandwidth killing useless posts like this in the future.

whoever thinks that 0.9999... does not equal 1 is a total dumbass.

It's not about philosophy or anything. This is straight up math. 0.9999infinity = 1. end of discussion.

Mathmatically it's not possible. One day you will learn. Just like in elementary school they told you that the square root of a negative number isn't possible and then later they tell you it is, later they will tell you technically .99R does not equal 1.

this is hilarious. .9R IS equal to one. It's the advanced math classes that let you realize this. But for all you high school kids out there...

1/3 = .33R
+ 2/3 = .66R
---------------
3/3 = .99R = 1

Not mathematical at all, but gets the point across

that's got to be the worst attempt at a proof I've ever seen.

It's real easy to prove to the simple minded non math types.

What's the difference between 1 and 0.9999...? When you can answer that you'll understand.

Funny sidenote: I got a PM (from someone who shall remain nameless) that said "1 does not equal 0.999"

I wrote back: "I know."

hehe

I've come to realize that anyone who doesn't accept that they are exactly equal are never going to accept the truth, despite seeing the proof
