The Pi (π) Files


Facts and Figures about Pi .

An Example of Why you should never trust Unverified Values from ANY Internet site .
I've always told students, " You should use at least three different sources when studying a particular subject, since you may, 1) have trouble understanding what one author says at times, or 2) wish to verify some questionable 'facts' presented by someone. But when you're trying to verify the validity of a number, use as many reliable sources as you can! "

From 1,000 To 1, 250, 000 Decimal Places of π !  A page for downloading accurate compressed files of π from The Starman.
 These files are 100% accurate: Being the result of a digital comparison (using "File Compare" programs) on files assembled from many independent and trustworthy sources (See the annotated listing of various sources in the table.)


50, 000 Decimal Places of π in HTML This displays all 50,000 digits in 10-digit groups, rather than just the raw digits (as in the files above).

100, 000 Decimal Places of π (and MD5 checksum) . This text file displays all 100,000 digits (plus the next 50 after that!) in 10-digit groups (50 digits per line) and 1000-digit blocks which are titled every 10,000 digits and separated every 5,000 digits so it's easy to find a particular digit if necessary!
( MD5 checksum of the file above is: cbd5ecc549d5d80bb8d024d8aa9b9687 ).
If you're using Linux/*nix, download from the link above which uses Unix-style (only 0Ah) returns. If you're using a PC with MS-DOS or Windows (uses 0Dh + 0Ah returns) download this ZIP archive of the text file: Pi100000.zip ( MD5 checksum included ).

Calculate Millions of Digits of Pi on Your Own Computer ! From an easy Windows 95 program to the latest FFT open source code program that will run on almost any system!

The "Randomness" of π.   Includes distribution GRAPHS of the digits and a discussion about searching for things meaningful in π. ( There's also a page linked to this one which describes how to calculate CHI-SQUARE for each sample distribution of π.)


Read The Randomness of Pi for more about the curious digit strings (such as the
"999999" or "360" in the pic above) that have been found in Pi.
