That REAL Pi actually ends at 7 digits. Discovered by a greengrocer named Dennis.

There's been an easy say to calculate it since 1800s using an abacus.

Edit: thought the /s was implied with, you know, "Dennis." I knew I should have gone with "Humperdink."

    I would like to learn more about this. Wiki says:

    In the 5th century AD, Chinese mathematicians approximated π to seven digits, while Indian mathematicians made a five-digit approximation, both using techniques.

    So it looks like they were all approximations, but it actually is much longer like I was always taught.
