Simon Plouffe & Neil Sloane do maintain the sole
world wide "Combinatorics" data based. Modern
Computing Machinery, when needed to compute "pi"
compute pi(n) ... attached. Note that Smath does

internally more accurate but unknown how Smath treats
such fraction for itself. Donald Knuth published the
mainy constants 40 decimals.
