Hi,

Programs to compute multiple digits of Pi are very commun, and a lot of versions for the HP-41 exist.

I decided to put online my own version for the HP-41 I wrote maybe 20 years ago, with it I got 560 digits in about 22h. There are better HP-41 programs that can still be found in PPC archives, but I didn't know them at the time, and I'm still proud of my program, I wrote it without any theoretical knowledge of multiprecision arithmetic.
