The Digits of Pi

The main mathematical news

1999: Roughly 206 Billion decimal digits of pi are known.

2002: Over 1 Trillion decimal digits were computed, by using 64 processors.

2010: Roughly 5 Trillion digits were computed.

2018: Roughly 22.4 Trillion decimal digits.

Tides are turning: π is used in order to test the performance of supercomputers and to improve high-precision algorithms.
