[Boost-users] question about boost::interval

Hi, I'm a little bit confused about the documentation in http://www.boost.org/libs/numeric/interval/doc/rounding.htm, in the subsection "Transcendental functions". Does the "Please note" paragraph means that the provided classes for transcendal functions (_opp and _std) do not guarantee the inclusion property? From what I understood it says that it depends on the implementation of the std::* math functions, that, in most cases, don't obey current rounding mode. Am I getting this right? In case I am, does anyone knows if I'm safe with gcc std library (perhaps by using the -frounding-math switch)? Thanks! Marco -- Marco Correia
