<h1>TODO list for the Interval Arithmetic library</h1>
<h2>Comments from the review process</h2>
<ul>
<li>It would be nice to have a 100% portable Rounding policy class based
on LIA-1 only, with no additional requirement such as IEEE 754 or even
more.</li>
<li>For pi and other constants, we should fetch them from the Math
constants library when it is ready.</li>
</ul>
<h2>Various items</h2>
<ul>
<li>Support the <code>-mfpmath=sse</code> option of g++ for Pentium IV
optimized code. This requires a different rounding policy class.</li>
<li>Have an optimized specialization of
<code>interval&lt;double&gt;</code> using SSE2 instructions? Tricky.</li>
<li>Write a traits specialization for <code>interval&lt;MPFR&gt;</code>,
and other non-built-in number types.</li>
<li>Have a robust implementation of transcendental functions over the
built-in floating point types (e.g. using MPFR)?</li>
<li>Safe conversions from <code>interval&lt;double&gt;</code> to
<code>interval&lt;float&gt;</code>? Requires partial specialization.</li>
<li>It would be nice to use the expression template mechanism to
automatically use the more efficient unprotected rounding mode version
for small subexpressions (although you can do bigger expressions by
hand).</li>
</ul>
