Now see how long it takes your computer to come up with a practical real-life application for needing "pi" beyond ten decimal places. Ancient Egypt existed on the basis of "pi" = 22/7, a gross approximation. If I need it, I just look it up in a book I have where it's listed to 100,000 decimal places -- still pointless.
The calculation of "pi" doesn't take but a simple reiterative loop (was that right from the Department of Redundancy Department or not?) that gradually sharpens the calculation's precision.
Computer speed is folly. The only reason for the need of high-speed PCs is the fact that software has become so huge and inefficient that it takes large hard drives, a lot of RAM and high processor speed to run it. Except for the glitz of WYSIWYG and such other superfulous bells and whistles, my WordStar 3.3 word processor ran just as fast on a 4MHz, MS-DOS, dual 5.25" floppy, no HDD, 640KB RAM machine as my current obese word processing program does on this hp Pavilion (and with fewer glitches). With the exception of some math-intensive programs such as a full-blown version of AutoCAD/AutoSHADE, speed only compensates for programming laziness. The devil is behind it all.
