Hang on, hang on, now I'm getting confused.
First you asked for the smallest (positive) x such that
1+x /= x
which is around x=4.5e15.
Then Joachim wondered if you wanted
1+x /= 1
which is around x=2.2e-16.
But not you claim to be looking for the smallest positive number that
a Double can represent. Which is a totally different beast. The
smallest possible Double depends on if you want to accept
denormalized numbers or not. If you don't, then it's about x=4.5e-308.
Now what is the number you are looking for?

Tamas,
You might want to read Joachim's post more carefully - he's trying to
help you, and I think he makes a good point.
Chad,
If his point is that there is no smallest positive number, then I
think I understand it, thanks. I should have said that I was looking
for the smallest positive number Double can represent, but thought
that was clear from the context.
If this is not his point, I'd really appreciate an explanation.
Thanks,
Tamas
