|---|
| 15 | |
|---|
| 16 | <h2>Comments from the review process</h2> |
|---|
| 17 | |
|---|
| 18 | <ul> |
|---|
| 19 | <li>It would be nice to have a 100% portable Rouding policy class based |
|---|
| 20 | on LIA-1 only, with no additional requirement such as IEEE 754 or even |
|---|
| 21 | more.</li> |
|---|
| 22 | |
|---|
| 23 | <li>For pi and other constants, we should fetch them from the Math |
|---|
| 24 | constants library when it is ready.</li> |
|---|
| 25 | </ul> |
|---|
| 26 | |
|---|
| 27 | <h2>Various items</h2> |
|---|
| 28 | |
|---|
| 29 | <ul> |
|---|
| 30 | <li>Support the <code>-mfpmath=sse</code> option of g++ for Pentium IV |
|---|
| 31 | optimized code. This requires a different rounding policy class.</li> |
|---|
| 32 | |
|---|
| 33 | <li>Have an optimized specialization of |
|---|
| 34 | <code>interval<double></code> using SSE2 instructions? Tricky.</li> |
|---|
| 35 | |
|---|
| 36 | <li>Write a traits specialization for <code>interval<MPFR></code>, |
|---|
| 37 | and other non-built-in number types.</li> |
|---|
| 38 | |
|---|
| 39 | <li>Have a robust implementation of transcendental functions over the |
|---|
| 40 | built-in floating point types (e.g. using MPFR)?</li> |
|---|
| 41 | |
|---|
| 42 | <li>Safe conversions from <code>interval<double></code> to |
|---|
| 43 | <code>interval<float></code>? Requires partial specialization.</li> |
|---|
| 44 | |
|---|
| 45 | <li>It would be nice to use the expression template mecanism to |
|---|
| 46 | automatically use the more efficient unprotected rounding mode version |
|---|
| 47 | for small subexpressions (although you can do bigger expressions by |
|---|
| 48 | hand).</li> |
|---|
| 49 | </ul> |
