YOU do not get to decide where Jesse, or anyone else of that matter, is

constrained to work. He doe snot appear to want to work under the

constraints you wish to impose on him, and you have no power to make him

do so.

It is a question that has already been answered affirmatively everywhere

outside Wolkenmuekenheim.

But does every real accessible real have a decimal expansion, at least

in theory?

Does every rational have a decimal expansion?

If yes to either of the above then there can be no objection to infinite

decimal expansions.

WHat none of us can comprehend is why you say it, and keep on saying it,

when it is so patently obvious that no one else believes it, and that no

one will believe it from anyone as incompetent at logical argument as

you have repeatedly proved your serf to be.

Since in 0.777... = sum_(n in |N) 7/10^n there is a digit for every

natural n in |N ,, what need is there for any digit BEYOND every natural?

WM seems to be arguing that there is something in |N that is beyond

every n in |N but still in |N.

First you show that there needs to be some n in |N a member which lies

beyond every other m in |N.

Terminating digit sequences have a last digit, non-terminating don't.

It is perhaps possible but inappropriate for the problem of 0.777...

In working with something like 0.777..., it is much better to work in a

system in which 0.777... can actually occur that to work in a system

where it cannot occur.

But that would make WM'sa foolishness obvious to everyone, so that WM

insists on being an ass anyway.

> Why can't you support your claims?

Jesse makes no claims, but only asks questions about 0.777... which WM

fails to answer.
