Continued Fraction of Primes
If one knows
x=1/(2 + 1/(3 + 1/(5 +1/(7 +1/(11 ..., he can easily produce the list of all primes, but what does x equal to by itself?

That is fake!
Is it possible to calculate the fraction without the beforehand knowing of all primes ?

Have you ever studied infinite series in a math class? There are techniques for calculating the sum of an infinite series once the general formula for each term is known, even though not all the specific values are known. Continued fractions can be similarly calculated.

None can give a form for nmember of such kinda series, which convergence to continued fraction of all primes.

Okay, you're right. It's not possible. The number is fake. I was blowing smoke, and you called me on it.

I guess he can take it up with Michael Hartley now.

Consider the continued fration
x=1+1/(2+1/(3+1/(4+1/(......... I've calculated the value of x and got this result: [code:1]x=1.4331274267 2231175831 7183455775 9918204315 1276790598 0523434428 6363943091 8325417290 0136503726 4357861146 5950013404 3088536429 5301770827 3894637360 4073219525 3363524736 8315637151 3409658626 2656344480 856171979[/code:1] Is there a formula of the exact x value now?[/code]
