Later computers calculated pi to extraordinary numbers of digits (2.7 trillion as of August 2010), [4] and people began memorizing more and more of the output. The world record for the number of digits memorized has exploded since the mid-1990s, and it stood at 100,000 as of October 2006. [ 6 ]
Haraguchi holds the current unofficial world record for reciting 100,000 digits of pi in 16 hours, starting at 9:00 a.m. (16:28 GMT) on October 3, 2006.
