Floating Point Utilities Review Result. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ There were 6 positive reviews and no negative ones, so Johan Rade's Floating Point Utility library has been accepted into Boost. The main issues and topics that came up for discussion were: 1) A couple of minor bugs were uncovered relating to signed NaN testing when using the SSE2 registers, and deserialising NaN's: both were fixed during the review period. 2) We had a discussion about the usefulness or otherwise of signed NaN's and the changesign function: Johan agreed to drop support for these as the signbit of NaN's is not considered part of the NaN payload and need not be preserved by the compiler, this could usefully be summarised in a rationale: especially now that negative NaN's are not formatted with a "-" sign? 3) JM made a few quite fruitless suggestions about optimising away calls to memcpy: this should be documented in a rationale to prevent JM from making the same mistake again :-) 4) John Phillips raised the issue of finding these tools - making sure that they don't get lost amongst all the other special functions and "stuff" in Boost.Math. JM and Johan have agreed to work together to ensure this doesn't happen. 5) There were a couple of suggestions for a convenience function for installing the facets in a locale/iostream: Johan agreed to add this. 6) There was +1 vote for manipulators rather than flags to the facet constructors - further investigation suggested this was problematic in a header only library - so the suggestion was dropped. 7) There was one comment about the library not using quickbook for documentation: ideally it would be nice to see this fixed so that the docs integrate seamlessly with the rest of Boost.Math - but see #4 as well. Many thanks to Johan for making these utilities available. John Maddock.
