- For those functions that are based upon the <a class="link" href="../lanczos.html" title="The Lanczos Approximation">Lanczos
- approximation</a>, the bindings defines a series of approximations with
- up to 61 terms and accuracy up to approximately 3e-113. This therefore sets
- the upper limit for accuracy to the majority of functions defined this library
- when used with either <code class="computeroutput"><span class="identifier">mpfr_class</span></code>
- or <code class="computeroutput"><span class="identifier">mpreal</span></code>.

There is a concept checking test program for mpfr support <a href="../../../../../../libs/math/test/mpfr_concept_check.cpp" target="_top">here</a>
and <a href="../../../../../../libs/math/test/mpreal_concept_check.cpp" target="_top">here</a>.
