I'm sure you've been at a2k long enuf to have heard that question asked and answered a million times by now:

(1) ignore doesn't make it impossible to see a person's posts
(2) ignore isn't permanent
(3) ignore doesn't stop you from seeing a person when surfing the site in offline mode

Infinite .9s will get u all the way to ALMOST 1. (Beyond that point is fakery and your wishful thinking.)

@OmSigDAVID,
Everything you said could apply equally to the case of 0.333... and 1/3.

0.3 Not Equal 1/3
0.33 Not Equal 1/3
No matter how many 3's you add after the decimal point you will not get to 1/3.

And yet most people in math are fairly comfortable with the idea that 0.333... = 1/3.

Agreed. This thread (falsely) alleges that "O.99999.....= 1".
I rose in DENIAL of liberal math (i.e., in denial of a hoax).
I am content with that; I ratify my position of negation.

Let THEM defend their errant, liberal comfort. I am not responsible for their errors.
For that matter, thay elected obama (with no help from me).
Its not MY fault.

It does, UNLESS u peek,
thereby nullifying n voiding the whole point of Ignore.

The hell, its not. In the last 1O years,
I 've put about 2O people on Ignore; its almost always been a 1-way trip.
I 'm a fairly patient fellow; I 've only dumped the very most perniciously toxic
abusers into the dungeon.
Seldom have I let any out again.
In truth, there r a couple who have proven their worthiness to be free.
One sick mind that I can think of, after about a year of freedom
was grossly noxious to someone else. I stuffed him back into Pandora's Box,
where he 's remained for the last 2 years or so.

U were a bit ruff with someone when I first saw your post,
so I addressed u in the same tenor b4 u detonated; your choice.
I love the filosofy of Patience and Prudence, to wit:
"Got along without u b4 I met u, gonna get along without u now."

I never thought of that.
If u put him on Ignore, then Y wud u WANT to do that ??

@OmSigDAVID,
David, based on what you are saying there is no e or pi, because both of them are irrational numbers.

.999... is simply a special case of an irrational number.

Just like 3.14159..yadayada = pi, we have .99999999... = 1

I'm sorry that math and the rest of the universe is incompatible with your conservative views. I'm sorry that your world view does not encompass anything more complex than flint hatchets, but the rest of the universe is not so constrained.

I suspect you'll have similar difficulty with the infamous double-slit experiment.

Fortunately, your ignorance doesn't affect reality; have fun in your little fantasy of how math works, but I won't be joining you.

@DrewDad,
0.99999999.... is not irrational. It's a rational number. An irrational number cannot be expressed as a ratio of two integers

0.999999...=1/1

so by definition its rational.

to OmSigDAVID perhaps math is too crisp for most attending attorneys---fortunately that wasn't true for Fermat.

In the name of logic, u exhort inconsistency.
DEFINITIONALLY, .9999 etc. is something less than 1. It is almost, but not quite, 1.
In the same breath, u deny that it is one and u affirm that it is. U rape logic.

Great! Feel free to share your definition of what 0.999... is with us.

I've given a definition already. I think the sum 0.9 + 0.09 + 0.009 + ... is how we should formally define 0.999... in order to get at the heart of what 0.999... represents.
What's your definition?

Dayvid, I always had you pegged as one of them liberal types who would never shoot a child for stealing a crust of bread without shouting a warning first!

But as I consider any New Yorker my brother and seaing as how you are under sustained fire from a pack of a>kademmicks; not that I’m sure they are all Irish - so I will supply subdiffusion in support of your premise thus allowing you time for a tactical withdrawal…

Whilst waiting for Democrats to get out their crayons, consider:

.999...= x.
x can NOT BE EQUAL TO ANYHING ELSE BUT .999

Do you know why?
Because I just define x to be equal to .999.... So adding any other number would break the constraint I placed it. That is the only possible solution.

X represents a number in which it's value may not be known but it doesn't have to be equal to any number in the number spectrum. It is not a paramater. We are aloud to make x be define by making it equate to something

.999.. (multiplied by ten) = 9.999.....
x (multiplied by ten) = 10x

I think we can agree with x being equal to ten x and that is not a problem. So for the one above the argument often is that a 0 will be added to the end and shift everything to the decimal place.

But let's not forget that we know there is an infinite amount of 9's. So let's say we add a 0 at the end of an infinite amount of nines. That would make sense but let's not forget it is placed after the infinite amount of 9's.

So .999(after infinite amount of 9's) 0 = 10x
Ok now let's get to the interesting part
9.999 (after infinate amount of 9's ) 0 = 10x
- .999 (infinte amount of 9's) = X

Let's agree now that we can add a infinite amount of zeros after the infinite amount of 9's which is always assumed that we can add as many zeros afterwards in the decimal place and it does not affect the number .0010 = .001

So that means this can be rediscribed as
9.999 (after infinate amount of 9's) 0 = 10x
- .999 (after infinate amount of 9's) 0 = x _______________________________________________
9 = 9x
Now because of this we can do a simple subtraction to get this result. And of course from here.
1 = x


Ipso facto quid pro quo!

I do. If thay add more 9s,
then that 'll be a DIFFERENT NUMBER, which is non-X.

No doubt.

@OmSigDAVID,
Ignore. Your reasons are subjectively-based, and not really explaining the point, but, if you feel that's how you think 0.999... = 1, okay. I wasn't sure of it either.

@Logicus,
Ultimately, according the laws of real analysis, I don't think there is any way to define 0.999... to be a real number and have it be less than 1.
However, there may be hope for David's view in the realm of hyperreal numbers.

A hyperreal number is an infinite sequence of real numbers.

Standard real numbers, when considered in their hyperreal representation, are just constant sequences:

1 = (1, 1, 1, 1, ...)
0.9 = (0.9, 0.9, 0.9, 0.9, 0.9, ...)

I'm wondering whether the natural representation for 0.999... as a hyperreal would be:
0.999... = (0.9, 0.99, 0.999, ...).

This would give 0.999... two desirable properties:
(i) 0.999... < 1
(ii) For all real x < 1, x < 0.999...

I believe that David has echoed the views of many from this site who have not posted in this thread. It is intuitive that 0.999... < 1. When the laws of mathematics (its definitions and axioms) give us a result that disagrees with most people's intuition, one answer is to find a new set of axioms and definitions.
