|
|
|
|
|
|
|
|
|
|
<p><a href="http://www.openlibm.org">OpenLibm</a> is an effort to have a high quality, portable, standalone
|
|
|
|
|
C mathematical library (<a href="http://en.wikipedia.org/wiki/libm"><code>libm</code></a>).
|
|
|
|
|
It can be used standalone in applications and programming language
|
|
|
|
|
implementations.</p>
|
|
|
|
|
|
|
|
|
|
<p>The project was born out of a need to have a good <code>libm</code> for the
|
|
|
|
|
<a href="http://www.julialang.org">Julia programming langage</a> that worked
|
|
|
|
|
consistently across compilers and operating systems, and in 32-bit and
|
|
|
|
|
64-bit environments.</p>

|
|
|
|
|
|
|
|
|
|
<p>The OpenLibm code derives from the <a href="http://svnweb.freebsd.org/base/head/lib/msun/">FreeBSD
|
|
|
|
|
msun</a> and <a href="http://cvsweb.openbsd.org/cgi-bin/cvsweb/src/lib/libm/src/">OpenBSD
|
|
|
|
|
libm</a>
|
|
|
|
|
implementations, which in turn derive from <a href="http://www.netlib.org/fdlibm/">FDLIBM
|
|
|
|
|
5.3</a>. Over and above that, OpenLibm itself has received a number of patches to make it platform independent and portable.</p>

<p>OpenLibm builds on Linux, macOS, Windows, FreeBSD, OpenBSD, NetBSD, and
|
|
|
|
|
DragonFly BSD. It builds with both GCC and clang. Although largely
|
|
|
|
|
tested and widely used on the x86 and x86-64 architectures, OpenLibm
|
|
|
|
|
also supports arm, aarch64, ppc64le, mips, wasm32, and s390(x).
