Bailey-Borwein-Plouffe formula

A base-b BBP-type formula is a convergent series formula of the type α = sum_(k = 0)^∞ (p(k))/(b^k q(k)) where p(k) and q(k) are integer polynomials in k (Bailey 2000, pp. 54 and 128-129). Bailey and Borwein and Bailey give a collection of such formulas. The following extends those compilations to include several additional BBP-type formulas.
