How many digits has pi been solved?


I believe that the current "record" for digits of pi solved stands at 51.5396 billion decimal digits; set by Yasumasa Kanada.

More Info:

Yasumasa Kanada (金田 康正 Kanada Yasumasa?, born 1949) is a Japanese mathematician most known for his numerous world records over the past three decades for calculating digits of π. He has set the record 11 of the past 21 times.

Kanada is a professor in the Department of Information Science at the University of Tokyo in Tokyo, Japan.


Mathematical analysis is a branch of mathematics that includes the theories of differentiation, integration, measure, limits, infinite series, and analytic functions. These theories are usually studied in the context of real and complex numbers and functions. Analysis evolved from calculus, which involves the elementary concepts and techniques of analysis. Analysis may be distinguished from geometry. However, it can be applied to any space of mathematical objects that has a definition of nearness (a topological space) or specific distances between objects (a metric space).

This page is about the history of approximations for the mathematical constant pi (π). There is a table summarizing the πchronology of computation of . See also the πhistory of for other aspects of the evolution of our knowledge about mathematical properties of π.


Super PI is a computer program that calculates pi to a specified number of digits after the decimal point—up to a maximum of 32 million. It uses Gauss–Legendre algorithm and is a Windows port of the program used by Yasumasa Kanada in 1995 to compute pi to 232 digits.
