.9r was the OP's shorthand for .999... to infinity. This is just "his"
definition, but it will do for the illustration.
=====================================
Oh, ok, a notation problem. Perhaps 0.9\ would be an improvement,
the backslash is underused.
=====================================
An old fashioned method of
dealing with people who snip the main point of the argument is to
give them the same treatment.
How does one deal with having none of one's post included other than
one's name?

If h were what we call a "real" number, it would be divisible by any
other real number except zero. That is because real numbers are
defined as a field with operations addition, subtraction,
multiplication and division applicable to every pair of real numbers
except for division by zero.
===============================================
I didn't say h was a real number. h bridges the gap between reals and
rationals.
No big deal, it's just a convenience.
There is no gap between the reals and the rationals.
====================================
There is now. (snip)
If you ever think
=========================
I do that often; you should try it for once in your life, you snipping
fuckwit.
To the Romans, zero was not a number of any previously invented kind.
The natural numbers do not include zero, but the integers do.
Not having zero meant the Holy Roman Empire produced no mathematicians.
0 (zero) is a symbol that represents nothing.
The vector (x,y,z,0,0,0,0) is just as valid as (x,y,z).
h is simply a symbol to represent a concept. One can't divide by zero
but one can divide by h.
I didn't invent h (or delta or epsilon by any other name), Bonehead,
but I may be the first person to give it official recognition as a
special number like zero, 1, e, pi, because if you don't name entities
then they get forgotten or confused.
In the group (R, *) zero doesn't exist, but h does.
The pathetically confused dork Einstein didn't name his "system of values"
"If we place x'=x-vt, it is clear that a point at rest in the system k must
have a system of values x', y, z, independent of time."

That's why you are not a mathematician, Bonehead. You are
one of his suckers. Don't feel bad, lots of people are.

As a consequence, there is no smallest real number greater than zero, <snip>
================================================
Ok, there is no such real number as zero because it has special properties.
That's fucking silly, isn't it?
Your brain is stuck in gear, Bonehead. You are way too old to be
a philosopher, you are senile.
