<a href="../../../../../../libs/multiprecision/doc/html/index.html" target="_top">Boost.Multiprecision</a>
was a development from the <a href="http://calgo.acm.org/910.zip" target="_top">e_float
(TOMS Algorithm 910)</a> library by Christopher Kormanyos.
</p>
<p>
e_float can still be used with Boost.Math library via the header:
</p>
<pre class="programlisting"><span class="special">&lt;</span><span class="identifier">boost</span><span class="special">/</span><span class="identifier">math</span><span class="special">/</span><span class="identifier">bindings</span><span class="special">/</span><span class="identifier">e_float</span><span class="special">.</span><span class="identifier">hpp</span><span class="special">&gt;</span>
</pre>
<p>
And the type <code class="computeroutput"><span class="identifier">boost</span><span class="special">::</span><span class="identifier">math</span><span class="special">::</span><span class="identifier">ef</span><span class="special">::</span><span class="identifier">e_float</span></code>:
this type is a thin wrapper class around ::e_float which provides the necessary
syntactic sugar to make everything "just work".
</p>
<p>
There is also a concept checking test program for e_float support <a href="../../../../../../libs/math/test/e_float_concept_check.cpp" target="_top">here</a>.
</p>
<p>
<span class="bold"><strong>New projects are recommended to use <a href="../../../../../../libs/multiprecision/doc/html/index.html" target="_top">Boost.Multiprecision</a>
with <code class="computeroutput"><span class="identifier">cpp_float</span></code> backend instead.</strong></span>
