# Computation of Catalan's constant using Ramanujan's formula

We have used some formulas due to Ramanujan for the multiple precision computation of Catalan's constant <italic>C</italic> = 0.915 ··· . The algorithm has been implemented in Maple and <italic>C</italic> has been computed to 20,000 decimal places. The resulting program is very simple yet efficient. It computes <italic>N</italic> digits of C in &Ogr;(<italic>N</italic><supscrpt>2</supscrpt>) time and &Ogr;(<italic>N</italic>) space.
