> class money_put;

Class std::money_put encapsulates the rules for formatting monetary values as strings. The standard I/O manipulator std::put_money uses the std::money_put facet of the I/O stream's locale.

Type requirements

OutputIt must meet the requirements of LegacyOutputIterator.


Two standalone (locale-independent) full specializations and two partial specializations are provided by the standard library:

Defined in header <locale>
std::money_put<char> creates narrow string representations of monetary values
std::money_put<wchar_t> creates wide string representations of monetary values
std::money_put<char, OutputIt> creates narrow string representations of monetary values using custom output iterator
std::money_put<wchar_t, OutputIt> creates wide string representations of monetary values using custom output iterator

In addition, every locale object constructed in a C++ program implements its own (locale-specific) versions of these specializations.

int main()
    // using the IO manipulator
    std::cout << "american locale: "
               << std::showbase << std::put_money(12345678.9)<< '\n';
    // using the facet directly
    std::cout << "german locale: " ;
    auto& f = std::use_facet<std::money_put<char>>(std::cout.getloc());
    f.put({std::cout}, false, std::cout, std::cout.fill(), 12345678.9 );
    std::cout << '\n';
