Defines a series corresponding to a specific Ramanujan-formula.

Constructors

MkSeries
Fields terms :: factorialAlgorithm -> [Rational] The sequence of terms, the sum to infinity of which defines the series. getSeriesScalingFactor :: squareRootAlgorithm -> DecimalDigits -> Rational The ratio by which the sum to infinity of the sequence, must be scaled to result in Pi. convergenceRate :: ConvergenceRate The expected number of digits of Pi, per term in the series.
