Thanks for the comments, Bert and Mehmet! It is of course a serious
and interesting area to explore (and I'm aware of the chaos context;
I initially got into this areas year ago when I was exploring the
possibilities for chaos in fish population dynamics -- and they're
certainly there)!
But, befor
Yes.
See also Feigenbaum's constant and chaos theory for the general context.
Cheers,
Bert

I wouldn't blame R for floating-point arithmetic and our personal
feeling of what 'zero' should be.

There was a similar post before, for example see:

Greetings All!
With the Festive Season fast approaching, I bring you joy
with the news (which you will surely wish to celebrate)
that R cannot do arithmetic!
Usually, this is manifest in a trivial way when users report
puzzlement that, for instance,
sqrt(pi)^2 == pi
# [1] FALSE
which is the
