[boost] Review Request: Floating Point Utilities

I'm requesting a formal review of the Floating Point Utilities library. The library contains the following: 1. Floating point number classification functions: fpclassify, isfinite, isinf, isnan, isnormal (Follows TR1) 2. Sign bit functions: signbit, copysign, changesign (Follows TR1) 3. Facets that format and parse infinity and NaN according to the C99 standard. (These can be used for portable handling of infinity and NaN in text streams.) The library is available in the vault in the folder Math-Numerics. (I've posted this message before, but with the wrong subject line.) --Johan Råde
