Deep Pi  Some Results Message #5 Posted by Mark Taylor on 4 May 2005, 12:46 a.m., in response to message #1 by PHILIPPE
I've been running the Deep Pi program found on voidware.com on 3 different HP41CX's, each using an AC adapter, for several month now (continuously).
Originally, the Deep Pi program calculated 6 digits of Pi at a time. But it was discovered that in at least one instance the 6th digit in a group was off by 1.
Also, I modified the Deep Pi program by inserting a RUNSW and STOPSW to time the generation of each set of 6 digits. Those 2 commands appear at steps 2 and 9, respectively.
Some results:
The first 6 digits of PI (after the 3) take about 38 minutes. The "deeper" into Pi you go the longer it takes.
Digits 619 thru 625 took over 274 hours, nearly 11.5 days.
I'd never make it without the AC adapters plugged into the battery packs. I just love seeing my calculators really work. The Deep Pi program keeps my 41s cranking!
Thanks Hugh Steers, for sharing Deep Pi on voidware.com.
