[Boost-users] boost.interval for tracking floating point rounding errors

Hi, I'm curious if it is possible to make boost.interval more convenient to use for tracking floating point rounding errors. Currently, you run into problems if you do naive things like boost::numeric::interval<double> x(0.1); since the 0.1 value gets rounded once by the compiler before the interval constructor ever sees it. Also, things like boost::numeric::interval<double> y(2), z; z = 0.1 * y; have similar problems. -- Frank
