<a id="openlibm" class="anchor" href="#openlibm" aria-hidden="true"><span class="octicon octicon-link"></span></a>OpenLibm</h2>

<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>

<h3>
<a id="history" class="anchor" href="#history" aria-hidden="true"><span class="octicon octicon-link"></span></a>History</h3>

<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 derives from <a href="http://www.netlib.org/fdlibm/">FDLIBM
5.3</a>. As a result, it includes a number
of fixes and updates to FDLIBM that have accumulated over the years in
<code>msun</code>, and optimized versions of many functions.</p>

<h3>
<a id="platform-support" class="anchor" href="#platform-support" aria-hidden="true"><span class="octicon octicon-link"></span></a>Platform support</h3>

<p>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. Although largely tested on x86, it also includes experimental
support for ARM.
