Hi;

I think you will have to settle for a numerical result. I am not finding a simple form in terms of known constants.

Yes, that constant is called the nested radical constant, usually denoted C[sub]NR[/sub]. No closed-form expression for that constant currently exists.

Hi;

Looking at the literature there does not even seem to be a good upper and lower bound.

Also interesting is the Prime Nested Radical

and the Fibonacci Nested Radical

How do you know which digits are correct?

I am not following you? The calculation was done by M.

Just what you see in post #2 but to many more iterations.

Okay, but then, how do you know to how many digits the result is accurate?

You run the calculation to n iterations and then you run it to 2n. You compare digits. I have only ever seen it fail one time.

I can not remember, it was a pathological case where someone was making a stupid math point and totally ignoring the thing called practicality.

You mean, they were specifically looking for a case when it doesn't work?

So did I.

You did not read about the billion decimal places of pi?

Okay, just checking.

I remember reading about BBP type formulas. Has that anything to do with what you are saying?

Yes, he shows a sum that agrees with pi to over 1 billion places and then veers away.
