Works for me.
It's just awkward to represent in decimal
The fractions don't "simplify" it, they are a better representation.
Simplification implying discarding accuracy to achieve an end.
I'll agree with 1 = the sum of the infinite series 0.999.. strictly as a
simplification, because the result isn't likely to be significantly different.
But I don't agree that 1 = 0.999...
The key point is that by making the first statement, you are defining what
"sum of the infinite series" means, not stating the equality 1 = 0.999...

'Snot what I said.
1/3 is a precise representation, 0.3333 isn't
PI works, 3.141... isn't precise.
When you force any of these trancendentals into decimal form, you can't
represent them accurately. It's a fundamental limitation of the decimal form.

I would have a link to FINDU here in my signature line, but due to the
inability of sysadmins at TELOCITY to differentiate a signature line from
the text of an email, I am forbidden to have it.
