What is a PI file?
A PI file is a data file created by iPi, a program that calculates the digits of Pi. It stores the progress of a user's Pi calculation. iPi users can load a PI file to resume the calculation the file describes.
Pi is a mathematical constant that describes the ratio of a circle's circumference to its diameter. Notably, Pi is a never-ending number, whose digits stretch on into infinity.
Using 10101 Software iPi, mathematicians and other Pi enthusiasts can calculate the digits of Pi out to a lengthy number of decimal places. To prevent iPi users from having to start from scratch every time they open the program, iPi allows users to save an in-progress calculation as a PI file. They can load that PI file to quickly pick up where they left off previously.
How to open a PI file
You can open a PI file with 10101 Software iPi. Unfortunately, however, iPi is discontinued. Therefore, if you do not already have access to iPi, you likely will not be able to open your PI file.
