<p>
        The requirements on the <code class="computeroutput"><span class="identifier">Backend</span></code>
        template argument to <code class="computeroutput"><span class="identifier">number</span></code>
        are split up into sections: compulsory and optional.
      </p>
<p>
        Compulsory requirements have no default implementation in the library, therefore
        if the feature they implement is to be supported at all, then they must be
        implemented by the backend.
      </p>
<p>
        Optional requirements have default implementations that are called if the
        backend doesn't provide it's own. Typically the backend will implement these
        to improve performance.
      </p>
<p>
        In the following tables, type B is the <code class="computeroutput"><span class="identifier">Backend</span></code>

        When the tables above place no <span class="emphasis"><em>throws</em></span> requirements on
        an operation, then it is up to each type modelling this concept to decide
        when or whether throwing an exception is desirable. However, thrown exceptions
        should always either be the type, or inherit from the type <code class="computeroutput"><span class="identifier">std</span><span class="special">::</span><span class="identifier">runtime_error</span></code>.
        For example, a floating-point type might choose to throw <code class="computeroutput"><span class="identifier">std</span><span class="special">::</span><span class="identifier">overflow_error</span></code>
        whenever the result of an operation would be infinite, and <code class="computeroutput"><span class="identifier">std</span><span class="special">::</span><span class="identifier">underflow_error</span></code>
        whenever it would round to zero.

          The non-member functions are all named with an "eval_" prefix
          to avoid conflicts with template classes of the same name - in point of
          fact this naming convention shouldn't be necessary, but rather works around
          some compiler bugs.
