C ++货币输出 [英] C++ currency output

问题描述

我现在正在上一门C ++课程，并完成了我的最终作业。但是，有一件事困扰着我：

I am taking a C++ course right now and have completed my final assignment. However there is one thing that is bugging me:

尽管我具有针对特定输出进行测试的正确输出，但 basepay 应为 133.20 ，并显示为 133.2 。有没有办法让它显示额外的0而不是将其保留？

Though I have the correct outputs for the testing on a particular output, the basepay should be 133.20 and it is displaying as 133.2. Is there a way to have this display the extra 0 rather than leaving it off?

任何人都知道这是否可行以及如何做到？预先谢谢

Anyone know if it's possible and how to do it? Thank you in advance

我的代码如下：

cout<< "Base Pay .................. = " << basepay << endl;
cout<< "Hours in Overtime ......... = " << overtime_hours << endl;
cout<< "Overtime Pay Amount........ = " << overtime_extra << endl;
cout<< "Total Pay ................. = " << iIndividualSalary << endl;
cout<< endl;

cout<< "%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%" <<endl;
cout<< "%%%% EMPLOYEE SUMMARY DATA%%%%%%%%%%%%%%%%%%%%%%%" <<endl;
cout<< "%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%" <<endl;
cout<< "%%%% Total Employee Salaries ..... = " << iTotal_salaries <<endl;
cout<< "%%%% Total Employee Hours ........ = " << iTotal_hours <<endl;
cout<< "%%%% Total Overtime Hours......... = " << iTotal_OvertimeHours <<endl;
cout<< "%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%" << endl;
cout<< "%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%" << endl;

推荐答案

使用 cout.precision 设置精度，然后已固定以切换定点模式：

use cout.precision to set precision, and fixed to toggle fixed-point mode:

cout.precision(2);
cout<< "Base Pay .................. = " << fixed << basepay << endl;
