What are some continued fractions for 2*pi and for pi/2 ?

[Guest]

Hello.

I've found on Wikipedia three simple and beautiful continued fractions for [tex]\pi[/tex], see this image:

I would like to see some continued fractions for [tex]2\pi[/tex] and for [tex]\frac{\pi}{2}[/tex].
As many as you can find. But I would want them to be simple and beautiful, like the previous three continued fractions.

Thanks in advance for your answers.
