C++ currency output - c++

Question

I am taking a C++ course right now and have completed my final assignment. However there is one thing that is bugging me:
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?
Anyone know if it's possible and how to do it? Thank you in advance
My code is below:
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;

Answer 1

If you want to do it in a C++ way, and you can compile with C++11 flags, you can use the standard library:
// Note: the value in cents!
const int basepay = 10000;
// Create a stream and imbue it with the local configuration.
std::stringstream ss;
ss.imbue(std::locale(""));
// The stream contains $100.00 (assuming a en_US locale config)
ss << std::showbase << std::put_money(basepay);
Example here.
What advantages have this approach?
It uses the local configuration, so the output will be coherent in any machine, even for the decimal separator, thousand separator, money symbol and decimal precission (if needed).
All the format effort is already done by the std library, less work to do!

Answer 2

use cout.precision to set precision, and fixed to toggle fixed-point mode:
cout.precision(2);
cout<< "Base Pay .................. = " << fixed << basepay << endl;

Answer 3

Yes, this is possible to do using stream manipulators. For example, set output to fixed floating-point notation, define precision (2 in your case) and define the fill character to '0':
#include <iostream>
#include <iomanip>
int main()
{
double px = 133.20;
std::cout << "Price: "
<< std::fixed << std::setprecision(2) << std::setfill('0')
<< px << std::endl;
}
In case you prefer a C-style formatting, here is an example of using printf() to achieve the same:
#include <cstdio>
int main()
{
double px = 133.20;
std::printf("Price: %.02f\n", px);
}
Hope it helps. Good Luck!

Answer 4

Check this out:
int main()
{
double a = 133.2;
cout << fixed << setprecision(2) << a << endl;
}
Output
133.20

Answer 5

You can change the cout properties:
cout.setf(ios::fixed);
cout.precision(2);`
now cout << 133.2; will print 133.20

Answer 6

You need to take a look at precision and fixed.
#include <iostream>
int main()
{
double f = 133.20;
// default
std::cout << f << std::endl;
// precision and fixed-point specified
std::cout.precision(2);
std::cout << std::fixed << f << std::endl;
return 0;
}
