Pi is familiar in school with π = 3.14...

It is the ratio of the length of the circumference of a circle to its diameter, and is an irrational number with an infinite number of digits after the decimal point.

We have made an e-book of pi, up to one million and one decimal places.

It is unrelated to the already popular book "Table of 1000000 digits of Pi", but pi is the same.

This is an e-book, so it is searchable.

In some places, we have also included the year and the name of the person who calculated it in the corresponding digit.

Please think back to the history of the calculation of pi for mankind.

As an added bonus, we have included a page that performs 1,000-digit calculations in real time.

You can feel the difference in the speed of convergence.

This is a reflow type e-book, so it will take some time to open.

When reflowed, it may be difficult to keep track of the number of digits. Please be patient.

Please enjoy the tightly packed numbers.
