Thanks!
Why does the the following simple code output "605mi h^-1" instead of "605 mi/h"? Why is the "^-1" at the end?
#include <iostream> #include <boost/units/base_units/us/mile.hpp> #include <boost/units/base_units/metric/hour.hpp> #include <boost/units/io.hpp>
using namespace boost::units; using namespace std;
typedef us::mile_base_unit::unit_type mile_unit; typedef metric::hour_base_unit::unit_type hour_unit; typedef divide_typeof_helper<mile_unit, hour_unit>::type miles_per_hour;
int main() { quantity<miles_per_hour> mph = 605.0 * miles_per_hour(); cout << mph << endl; return 0; }
The output code does not give special status to exponents of -1, but just treats them consistently. If you want specialized output, see examples/composite_output.cpp for an example. Matthias
