Hi all,

Version 0.16 of mpmath is now available on the project website:

It can also be downloaded from the Python Package Index:

Mpmath is a pure-Python library for arbitrary-precision floating-point
arithmetic that implements an extensive set of mathematical functions. It
can be used as a standalone library or via SymPy
(, and is also available as a standard
component of Sage ( The versions in Sage
and SymPy will be updated soon.

For details about the new features in this version, see the following
blog post and the changelog:

Changes in 0.16 include new special functions (incomplete elliptic integrals,
inhomogeneous Bessel functions, Bessel function zeros, parabolic cylinder
functions), rewritten functions (Lambert W function, Airy functions), and
various other fixes and improvements. Support has also been added for new
extension code that will make mpmath 0.16 much faster in Sage,
particularly affecting elementary and hypergeometric functions.

My work on mpmath 0.16 was funded using resources from NSF grant DMS-0757627,
whose support is gratefully acknowledged. Special thanks to William Stein
for enabling this.
