<h3 class="subsection">D.14.10 Additional <code>mpfr</code> notes</h3>

<p>The <code>eq</code> and <code>urandomb</code> functions depend not only on the
<code>mpfr</code> library but on the <code>gmp</code> library
<a name="index-gmp-library"></a>
(<a href="http://ftp.gnu.org/gnu/gmp">http://ftp.gnu.org/gnu/gmp</a>). It&rsquo;s possible for them to be
unavailable on a host without <code>gmp</code> even if the rest of the
<code>mpfr</code> library is properly configured.
</p>
<p>The file <code>mpfr.c</code> in the <code>avram</code> source tree exports a
couple of functions that may be of use to C hackers interested in
further development of <code>avram</code> with <code>mpfr</code>. The functions
<code>avm_mpfr_of_list</code> and <code>avm_list_of_mpfr</code> convert between
the native representation for <code>mpfr</code> numbers and the caching list
representation used by <code>avram</code> (<a href="Type-Conversions.html#Type-Conversions">Type Conversions</a>). This
conversion is non-trivial because the numbers are not stored
contiguously.
