No, it equals 1, duh!

god damnit. Not this again.

There is no such thing as 0.000....1. You can't have something that comes after something that repeats infinitely.

Sure it is. It is what you get when subtract .99999... from 1.

No, that would be 0.

Does .0000.....2 = 0?

No, that would be 0.

Yes, that would be zero...and that is exactly his point.

We've had long (and painful to read) threads arguing whether or not .99999... = 1. It should be obvious that 1 - 0.99999... = 0.000...1, and that if .99999... = 1, then 0.000...1 = 0.

Here we go again.

Edit: yes, 0.000...2 is also zero. 0.000...X where X is anything will be zero.

I'm nipping this in the bud:

Consider the number 0.1.
This is equivalent to 10^(-1).
Then 0.01 = 10^(-2), 0.001=10^(-3), etc.
Then if there are n 0s between the decimal and the one, the number is 10^(-(n-1)), clearly.
Now we increase n arbitrarily, to 0.000...1:
lim (n->infinity) 10^(-(n-1)) = 10*lim (n->infinity) 10^(-n).
Now, consider ANY arbitrarily small number, call it a.
Then 10^(-n) < a if and only if n > -log a.
Since for any arbitrarily small number a, there is a FINITE n for which 10^(-n) < a, we then have that the limit as n->infinity of 10^(-n) <= 0.
But 10^(-n) > 0 for all real n. Then the limit as n-> infinity of 10^(-n) <=0 and >= 0.
Then limit as n-> infinity of 10^(-n) = 0.

Problem done. This solution is mathematically and logically complete, sound, and excepting any basic typos I've made, irrefutable. If this thread grows to 5 pages after this, I'm disowning people.

Isn't everyone?

1 - 0.0000...1 does not equal zero.

end thread.

Join the club, subscribe to the newsletter! 9/11 was a deliberate act by the US government, man never set foot on the moon, and indeed there is a number in our minds called 0.000...747. Infinity is a concept used by the man to hide THE TRUTH!!!

OMG! Look at the coincidence!
7+4=11.
7+(1/2 *4) = 9.

9....
1.....
1.....

you can't have 0.000....X ever...you can never tack on an "X" to the end b/c the end keeps on going forever.

But that's just an observation.

It's close enough. Your notation is wrong, but if you're asking something like "after a decimel point there's an infinite number of zeros followed by a 1, does this equal zero" then my answer is yeah, it's close enough to be insignificant to anything and everything, and thus may as well be zero.

 

[GasX]

In Soviet Russia the decimal rounds off you!

 

[BrownTown]

asking this question and posting the term "0.000...1" shows a complete lack of understanding of the notion of infinity. There is no such number as "0.000...1".

 

[IronWing]

This is why numbers are bad. We should just stick to booleans. Q = 1 or Q = 0 and there ain't nothing else to worry about.


Hmmm, I'm feeling like a .... Republican.

It doesn't matter. Do a search for the old thread - some people won't be convinced no matter how many sound proofs you post. Not coincedentally, these people admit to not having a strong background in math, although they still reason that they are correct, and the rest of the math world is wrong.
