Dear folks,
Our latest record
was established as the followings;
Declared
record: 68,719,470,000
decimal digits
Two independent calculation based on two different algorithms generated
68,719,476,736 (=2^36) decimal digits of pi and comparison of two generated
sequences matched 68,719,476,693 decimal digits, e.g., 43 decimal digits
difference. Then we are declaring 68,719,470,000 decimal digits as the
new world record.
