I have written a proof that 0.999... cannot be equal to one in the

While at the end of it all you may not fully agree with my proof, much
I as have never seen a proof asserting they were equal that I was able
to consider valid, I'm sure you will agree that the
ideas I present are not a simply rehashing of basic objections of
others before me.
Your "proof" is the usual mish-mash of inadequate definitions and
hand-waving.
The equality is straightforward once you have precisely defined 0.999...
A reasonable definition is that 0.999... is the limit of the sequence
0.9 0.99 0.999 ...
The members of this sequence are 1 - 10^n, and the limit is 1. Therefore
0.999... = 1.
So, before proceeding any further, what is *YOUR* definition of 0.999...?
