<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>

<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 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>

2019-12-10 03:53:47 +01:00
<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).
