Calculate Pi!

The advent of digital computers in the 20th century led to an increased rate of new π calculation records. John von Neumann et al. used ENIAC to compute 2037 digits of π in 1949, a calculation that took 70 hours. Additional thousands of decimal places were obtained in the following decades

Now YOU can calculate MILLIONS of decimal places of Pi on your own Mac! Calculate Pi is faster than any other commercial Pi calculation program on the planet. What an extremely geeky pleasure!

If you want to calculate Pi to a lot of places, this is the app for you. However, it does not appear to be multitasking friendly. I entered a very large number of decimal places and basically lost control of my machine while it crunched the numbers. Until it was done, I was unable to do anything.



I used this program for pi day. I made an illustration that starts off the number large then shrinks down and fill the whole image. It was fun. Thanks for this program.

Fun app!

I really wanted to use it to compare CPUs, however I'm only seeing 1 core being used. Could you make this multithread/core?
