Factory.Math.Implementations.Pi.BBP.Implementation

AUTHOR

Dr. Alistair Ward

DESCRIPTION

• Implements a Bailey-Borwein-Plouffe formula; https://mathworld.wolfram.com/PiFormulas.html
• Surprisingly, because of the huge size of the Rational quantities, it is a single call to Factory.Math.Summation.sum', rather than the calculation of the many terms in the series, which is the performance-bottleneck.

Functions

Arguments

:: Series

This Pi-algorithm is parameterised by the type of other algorithms to use.

-> DecimalDigits

-> Rational

Returns Pi, accurate to the specified number of decimal digits.
