Decimal Points

[PDB1982]

I trying to create a program that deals with money, and have it all figured out except one portion...I can't get all the decimals to have a monetary look, meaning only two decimal places. I know I can setprecision(2), and that would work for most numbers, but what if the number are mixed in their length?

Example of what I'm getting:
$12.501
$1254.0
$124.15
$10321
$1.1254

Is it possible to have them all round out to only two decimal places?

Are you doing something like the following? It works OK on my end for simple currency:

#include <iostream>
#include <iomanip>

int main()
{
    double values[] =
    {
        12.501,
        1254.0,
        124.15,
        10321,
        1.1256
    };
    const int sz = sizeof values / sizeof *values;

    std::cout.imbue(std::locale(""));

    for (int x = 0; x < sz; ++x)
    {
        std::cout << std::fixed << std::setprecision(2)
                  << '$' << values[x] << '\n';
    }
}

First you have to decide if :

1) You want to output up to 2 decimal
2) You want the actual value of the decimal to be 2 decimal places long.

Just add this to your coding before your variables:

cout.precision(3);
