[Boost-users] [interval][units] interval operators not working when inteval elements are quantities

Hi, Does anybody know what is missing in the boost.interval (or in the boost.units) to allow these operation. It seems that there is no other way than to make "interval/arith.hpp:operator/" more generic. -- Thanks, Alfredo #include<boost/units/systems/si.hpp> #include "alf/boost/units/interval.hpp" int main(){ boost::numeric::interval<double> iv(1.,10.); clog << iv << " " << 1./iv << endl; // ok, gives [1., 10] and [0.1,1.] boost::numeric::interval<quantity<si::length> > iv2(1.*si::meter, 10.*si::meter); clog << iv2 << " " << 1./iv2 << endl; // error: no match for ‘operator/’ in ‘1.0e+0 / iv2’ return 0; }
