Try static_cast.
could you give me an example? That is how should the statement
l2 = 1.0 * miles; // compile error
be modified?
l2 = static_cast<quantity<length, float>>(1.0 * miles);
Hmmmm - OK this looks promising, but I get another compiler error with MSVC 1>z:\projects\geflightquest\simulator2\solvecpp\flight.cpp(14) : error C2065: 'miles' : undeclared identifier it looks like I'm missing something; Here is the test program again - with all the headers. #include <boost/units/systems/si/length.hpp> #include <boost/units/base_units/us/mile.hpp> #include <boost/units/quantity.hpp> int main(int argc, char * argv[]){ using namespace boost::units; using namespace boost::units::si; using namespace boost::units::us; quantity<length, float> l1; l1 = 1.0 * meters; quantity<length, float> l2; l2 = static_cast<quantity<length, float> >(1.0 * miles); quantity<length, float> l3 = l1 + l2; return 0; }
