-higher precision). With the additional difference below, this implies that
-the <cite><acronym>MPFR</acronym></cite> results do not depend on the
-number of bits (16, 32, 64 or more) of the underlying architecture.</p></li>
-<li><p>As a consequence, <cite><acronym>MPFR</acronym></cite> uses a
-base-2 exponent, whereas in <cite><acronym>MPF</acronym></cite>, this
-is a base-2<sup>32</sup> or base-2<sup>64</sup> exponent, depending on
-the limb size. For this reason (and other internal ones), the maximum
-exponent range in <cite><acronym>MPFR</acronym></cite> is different
-(and smaller, if the exponent is represented by the same type as in
-<cite><acronym>MPF</acronym></cite>).</p></li>
-<li><p><cite><acronym>MPFR</acronym></cite> provides an additional rounding
-mode argument to its functions; furthermore, it is guaranteed that the
-result of any operation is the nearest possible floating-point value from
-the exact result (considering the input variables as exact values), taking
-into account the precision of the destination variable and the rounding
-mode. <cite><acronym>MPFR</acronym></cite> also says whether the rounded
-result is above or below the exact result.</p></li>
-<li><p><cite><acronym>MPFR</acronym></cite> supports much more functions
-(in particular transcendental functions such as exponentials, logarithms,
-trigonometric functions and so on) and special values: signed zeros,
-infinities, not-a-number (NaN).</p></li>

-<dt id="mpf2mpfr">2. How to convert my program written using
-<cite><acronym>MPF</acronym></cite> to
-<cite><acronym>MPFR</acronym></cite>?</dt>
-
-<dd><p>You need to add <q><code>r</code></q> to the function names, and to
-specify the rounding mode (<code>MPFR_RNDN</code> for rounding to nearest,
-<code>MPFR_RNDZ</code> for rounding towards zero, <code>MPFR_RNDU</code>
-for rounding towards plus infinity, <code>MPFR_RNDD</code> for rounding
-towards minus infinity). You can also define macros as follows:
-<code class="block-code">#define mpf_add(a, b, c) mpfr_add(a, b, c, MPFR_RNDN)</code></p>
-<p>The header file <samp>mpf2mpfr.h</samp> from the
-<cite><acronym>MPFR</acronym></cite> distribution automatically
-redefines all <cite><acronym>MPF</acronym></cite> functions in this
-way, using the default <cite><acronym>MPFR</acronym></cite> rounding
-mode. Thus you simply need to add the following line in all your files
-using <cite><acronym>MPF</acronym></cite> functions:
-<code class="block-code">#include <mpf2mpfr.h></code>
-just after the <samp>gmp.h</samp> and <samp>mpfr.h</samp>
-header files. If the program uses <cite><acronym>MPF</acronym></cite>
-internals (such as direct access to <code>__mpf_struct</code> members),
-additional changes will be needed.</p></dd>

-<dt id="no_libgmp">3. At configure time, I get the error: <q>libgmp not found or uses a different ABI.</q></dt>
-
-<dd><p>This test (<samp>checking for __gmpz_init in -lgmp</samp>) comes
-after the <samp>gmp.h</samp> detection. The failure occurs either because
-the <cite><acronym>GMP</acronym></cite> library could not be found
-(as it is not in the provided library search paths) or because the
-<cite><acronym>GMP</acronym></cite> library that was found does not have
-the expected <acronym title="Application Binary Interface">ABI</acronym>
-(<abbr>e.g.</abbr> 32-bit <abbr>vs</abbr> 64-bit). The latter problem can
-have several causes:</p>
-<ul>
-<li>A wrong libgmp library has been picked up. This can occur if you have
-several <cite><acronym>GMP</acronym></cite> versions installed on the
-machine and something is wrong with the provided library search paths.</li>
-<li>Wrong compiler options (<samp>CFLAGS</samp>) were given. In general, the
-presence or absence of the <samp>-m64</samp> compiler option must match the
-library <acronym title="Application Binary Interface">ABI</acronym>.</li>
-<li>A wrong <samp>gmp.h</samp> file has been picked up (if you have several
-<cite><acronym>GMP</acronym></cite> versions installed). Indeed, by default,
-<cite><acronym>MPFR</acronym></cite> gets the compiler options from the
-<samp>gmp.h</samp> file (with <cite><acronym>GMP</acronym></cite> 4.2.3
-or later); this is needed because <cite><acronym>GMP</acronym></cite> does
-not necessarily use the default <acronym>ABI</acronym>. The consequence is
-that if the <samp>gmp.h</samp> file is associated with a library using a
-different <acronym>ABI</acronym>, the <acronym>ABI</acronym>-related options
-will be incorrect. Hence the failure.</li>
-</ul>
-<p>Note: The <samp>config.log</samp> output gives more information
-than the error message. In particular, see the output of the test:
-<samp>checking for CC and CFLAGS in gmp.h</samp>; it should give you
-the default compiler options (from <samp>gmp.h</samp>).</p>

-<dt id="undef_ref1">4. I get undefined reference to <code>__gmp_get_memory_functions</code>.</dt>
-
-<dd><p>Note: this was mainly a problem when upgrading from
-<cite><acronym>GMP</acronym></cite> 4.1.4 to a later version,
-but information given below may still be useful in other cases,
-when several <cite><acronym>GMP</acronym></cite> libraries are
-installed on the same machine.</p>
-
-<p>If you get such an error, in particular when running
-<samp>make check</samp>, then this probably means that you are using
-the header file from <cite><acronym>GMP</acronym></cite> 4.2.x but the
-<cite><acronym>GMP</acronym></cite> 4.1.4 library. This can happen if
-several <cite><acronym>GMP</acronym></cite> versions are installed on
-your machine (<abbr>e.g.</abbr>, one provided by the system in
-<samp>/usr/{include,lib}</samp> and a new one installed by the owner or
-administrator of the machine in <samp>/usr/local/{include,lib}</samp>)
-and your include and library search paths are inconsistent. On various
-<acronym>GNU</acronym>/Linux machines, this is unfortunately the case
-by default (<samp>/usr/local/include</samp> is in the default include
-search path, but <samp>/usr/local/lib</samp> is <em>not</em> in the
-default library search path). Typical errors are:
-<samp class="block-code">undefined reference to `__gmp_get_memory_functions'</samp>
-in <samp>make check</samp>. The best solution is to add
-<samp>/usr/local/include</samp> to your <var class="env">C_INCLUDE_PATH</var>
-environment variable and to add <samp>/usr/local/lib</samp> to your
-<var class="env">LIBRARY_PATH</var> and <var class="env">LD_LIBRARY_PATH</var>
-environment variables (and/or <var class="env">LD_RUN_PATH</var>).
-Alternatively, you can use <samp>--with-gmp*</samp> configure options,
-<abbr>e.g.</abbr> <samp>--with-gmp=/usr/local</samp>, but <strong>this is
-not guaranteed to work</strong> (in particular with <samp>gcc</samp> and
-system directories such as <samp>/usr</samp> or <samp>/usr/local</samp>),
-and other software that uses <cite><acronym>GMP</acronym></cite> and/or
-<cite><acronym>MPFR</acronym></cite> will need correct paths too;
-environment variables allow you to set them in a global way.</p>
-<p>Other information can be given in the <samp>INSTALL</samp> file and
