This series is never-ending, the more the terms this series contains, the closer the value of X converges to Pi value. The BaileyBorweinPlouffe formula (BBP) for calculating PI was discovered in 1995 by Simon Plouffe. The Chinese remainder theorem is a powerful tool to find the last few digits of a power. There are two methods to calculate the value of pi in python: Method 1: Using Leibniz’s formula. Keep a limit to how far the program will go. We commonly know Pi3.14 or Pi22/7, but it is just an approximation for our ease. tan-1() is the Inverse Tangent function, and I use the Maclaurin series to calculate it: tan -1 (z) z - z 3 / 3 + z 5 / 5 - z 7 / 7 +. Python Code: """"Find PI to the Nth Digit -Įnter a number and have the program generate PI up to that many decimal places. It is based on the following formula: pi / 4 4 tan -1 (1 / 5) - tan -1 (1 / 239) This is Machin's formula and is exact. Note: Input a number and the program will generate PI to the nth digit Pi calculated to a record-breaking 62.8 trillion digits By Harry Baker published 17 August 2021 Supercomputer took 108 days to run the calculations. Create a Python project to get the value of Pi to n number of decimal places.
