Authors: Andrew R. Booker, Andreas Strömbergsson, Holger Then.
Purpose: Rigorous multi-precision computation of higher transcendental functions.
reasonably fast – All computations are tightly bounded.
rigorous – Multi-precision interval arithmetic is used along with rigorous error bounds.
easy to use – The user specifies the desired precision while the algorithm determines automatically the required bounds.
fairly general – For instance Γ(z) works for any complex argument, including poles.
Version: 1.0.3 which includes the following files
