Python bindings for CRlibm <http://lipforge.ens-lyon.fr/www/crlibm>_, an efficient and proven
correctly-rounded mathematical library.

CRlibm is a free mathematical library (libm) which provides:

implementations of the double-precision C99 standard elementary
functions,
correctly rounded in the four IEEE-754 rounding modes,
with a comprehensive proof of both the algorithms used and their
implementation,
sufficiently efficient in average time, worst-case time, and
memory consumption to replace existing libms transparently.

Installation

At the command line::

$ pip install crlibm

On Microsoft Windows pip will try first to download a binary
archive in wheel format, and if no such a wheel can be found for
your Python version, pip will try to compile the library. In
order to do so, it is strongly recommended to have MinGW-w64 <http://mingw-w64.org>_ installed under MSYS2 <https://msys2.github.io>, for instance by following the
instructions in <http://stackoverflow.com/a/30071634>.

Usage

In Python::

>>> import crlibm
>>> crlibm.exp_ru(1)
2.7182818284590455

>>> crlibm.exp_rd(1)
2.718281828459045
