OpenLibm is an effort to have a high quality standalone LIBM
|
||||
library. It is meant to be used standalone in applications and
|
||||
programming language implementations.
|
||||
|
||||
OpenLIBM builds on Linux, Mac OS X, and Windows, and with little effort,
|
||||
OpenLibm also includes the AMOS library from Netlib, which is
|
||||
a portable package for Bessel Functions of a Complex Argument
|
||||
and Nonnegative Order. AMOS contains subroutines for computing Bessel
|
||||
functions and Airy functions.
|

|

OpenLibm builds on Linux, Mac OS X, and Windows, and with little effort,
|
||||
should build on FreeBSD as well. It builds with both, GCC and clang.
|
||||
|

The OpenLIBM code derives from the FreeBSD msun implementation, which
