Calculating pi

[andrewferguson]

Hi,
How do I calculate pi using LiveCode?
I know that LiveCode has the built in pi constant, but I want more decimal places.
Also, I know I could just copy and paste pi from a website into my program, but the whole fun is having it go on and on and on...

One of the oddest is:

1/π = 2√2 / 9801 * ∑ (4k)! (1103 + 26390k) / (k!)^4 * 396^4k

The sum taken from 0 to infinity.

Ramanujan did this in his head.

This looks like it could be readily worked out with LC. A repeat loop could run the summation for a while.

EDIT. I have a feeling the digits get out of hand pretty soon...
