Re: [Boost-users] getting started with Boost::Units

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 #include #include

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::type miles_per_hour;

int main() { quantity 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
