Isaac Newton got up to 16 digits of pi when using his method or he calculated 3.1415926535897932
pi has not yet been calculated to that degree of precision.
actually pi is endless ,so no one has calculated the last digits yet , interestinly it isn't repeating either.. they have whole books on it, filled with the digits of pi.

Because Pi is known to be an irrational number it means that the digits never end or repeat in any known way. But calculating the digits of Pi has proven to be an fascination for mathematicians throughout history. Some spent their lives calculating the digits of Pi, but until computers, less than 1,000 digits had been calculated. In 1949, a computer calculated 2,000 digits and the race was on. Millions of digits have been calculated, with the record held (as of September 1999) by a supercomputer at the University of Tokyo that calculated 206,158,430,000 digits. (first 1,000 digits). However, learning 3.141, is all that is necessary. But you can go on and on, to infinity, and never find the exact circumference of a circle. I have only memorized 205 digits of pi; and yes I do use it to find the circumference of a circle.
The computer was HITACHI SR2201. But in 1999, they calculated even more decimal places (206,158,430,000) with the HITACHI SR8000.
