[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.
