As announced in November 2016, I’ve computed 22.4 trillion digits of pi. The first trillion decimal digits are now available for download.
Small data sets
If you’re only interested in the first thousand or the first million digits of pi, you can download them as text files (.txt) directly from the links below. Data sets with more digits are available from archive.org. One billion digits have already been available before.
The one trillion digit data set
A few days ago, I made a data set with one trillion decimal digits available for download. The digits are saved as zip-compressed text files in chuncks of one hundred billion digits. Each file has a size of 43.7 GB. In total you have to download more than 430 GB.

Interested in all 22.4 trillion digits?
Providing all 22.4 trillion digits of my world record computation online is currently not feasible. Transferring almost 9 TB of data over a 10 Mbit/s connection would take several months. One way of distribution is to copy them on one or several disks and ship them per mail. If you’re interested to obtain all digits of pi at the costs of the required disks, please send me a short notice.
What to do with the digits of π?
With the digits of pi you can do more than calculating a circle’s circumference or area. If you need some inspiration about what you could do with all these digits of pi, here are some sites to look at:
