  30         <a href="../../../../../../libs/multiprecision/doc/html/index.html" target="_top">Boost.Multiprecision</a>
  31         was a development from the <a href="http://calgo.acm.org/910.zip" target="_top">e_float
  32         (TOMS Algorithm 910)</a> library by Christopher Kormanyos.
  33       </p>
  34 <p>
  35         e_float can still be used with Boost.Math library via the header:
  36       </p>
  37 <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>
  38 </pre>
  39 <p>
  40         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>:
  41         this type is a thin wrapper class around ::e_float which provides the necessary
  42         syntactic sugar to make everything "just work".
  43       </p>
  44 <p>
  45         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>.
  46       </p>

  49         with <code class="computeroutput"><span class="identifier">cpp_float</span></code> backend instead.</strong></span>
