I want to get x = 1,234,567,890.098,765,432,1.

#include <iostream>

#include <string>

#include <iomanip>

#include <locale>

using namespace std;





struct separated : numpunct<char>

{

    string do_grouping() const { return "3"; }

};





int main()

{

    const double x = 1234567890.0987654321;

    locale our_local(cout.getloc(), new separated);

    cout.imbue(our_local);

    cout << fixed;

    cout << setprecision(10);

    cout << "x = " << x << endl;

    return 0;

}

Output: x = 1,234,567,890.0987654321

Expected output: x = 1,234,567,890.098,765,432,1

It will be much better if you can make it more general as follows,

• 
  x = 1'234'567'890.098'765'432'1


• x = 1_234_567_890.098_765_432_1

The decimal point is dot (US-EN).
