Description

AUTHOR

DESCRIPTION
  • Implements a Bailey-Borwein-Plouffe formula; http://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.
