A collection of Gnu MP/bignum arbitrary-precision algorithms for various special functions occurring in analytic number theory. Primarily implements functions and algorithms that are not (yet) in mainstream/popular packages, such as PARI/GP.
Includes Hurwitz zeta, Riemann zeta, polylogarithm, Minkowski question mark function, confluent hypergeometric function, GKW operator; all implemented in GMP. Also includes trig functions (sine, cosine, exp, log), gamma function, binomial coefficients, complex number type, assorted high-precision constants. Also includes routine for finding zeros of a complex-valued function (Powell's algo).
Users are encouraged to port the algorithms here to existing arbitrary-precision systems. The Anant system is *NOT* meant to be a strong stand-alone project, but rather a staging area for special functions and algorithms that have not yet received wide-spread attention.
