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;
}
