添加分钟和秒钟.以小时显示 [英] Add minutes and seconds. Display in hours

问题描述

假设我想添加29分60秒并以小时为单位显示结果.

Let's suppose I'd like to add 29 minutes and 60 seconds and display the result in hours.

这里似乎起作用:

cout <<
    static_cast<quantity<hour_base_unit::unit_type>>
    (quantity<time>{29.0 * minute_base_unit::unit_type()} + 60.0 * seconds)
    << endl;    

控制台上显示以下内容:

The following is displayed on the console:

0.5 h

这是推荐的方法吗?有没有更好或更惯用的方式?

Is this the recommended approach? Is there a better or more idiomatic way?

下面是说明上述示例的整个程序.

The entire program illustrating the above example is below.

#include <iostream>
#include <boost/units/systems/si/io.hpp>
#include <boost/units/systems/si.hpp>
#include <boost/units/base_units/metric/hour.hpp>
#include <boost/units/base_units/metric/minute.hpp>

using namespace std;
using namespace boost::units;
using namespace boost::units::si;
using namespace boost::units::metric;

int main()
{   
    cout <<
        static_cast<quantity<hour_base_unit::unit_type>>
        (quantity<time>{29.0 * minute_base_unit::unit_type()} + 60.0 * seconds)
        << endl;        

    return 0;
}

推荐答案

您可以做

(分钟/60 +秒/3600)

(minutes/60+seconds/3600)
