Restituisce un oggetto di tipo tale che, se non specificato out è il nome di un flusso di uscita di tipo std::basic_ostream<CharT, Traits>, allora l'espressione out << put_money(mon, intl) comporta come se il codice è stato eseguito il seguente:

Original:

Returns an object of unspecified type such that if out is the name of an output stream of type std::basic_ostream<CharT, Traits>, then the expression out << put_money(mon, intl) behaves as if the following code was executed:

typedef std::ostreambuf_iterator<CharT, Traits> Iter; typedef std::money_put<CharT, Iter> MoneyPut; const MoneyPut& mp = std::use_facet<MoneyPut>(out.getloc()); const Iter end = mp.put(Iter(out.rdbuf()), intl, out, out.fill(), mon); if (end.failed()) out.setstate(std::ios::badbit);

Esempio

#include <iostream>
#include <iomanip>
int main()
{
    long double mon = 123.45; // or std::string mon = "123.45";
    std::cout.imbue(std::locale("en_US.utf8"));
    std::cout << std::showbase
              << "en_US: " << std::put_money(mon) << " or " << std::put_money(mon, true) << '\n';
    std::cout.imbue(std::locale("ru_RU.utf8"));
    std::cout << "ru_RU: " << std::put_money(mon) << " or " << std::put_money(mon, true) << '\n';
    std::cout.imbue(std::locale("ja_JP.utf8"));
    std::cout << "ja_JP: " << std::put_money(mon) << " or " << std::put_money(mon, true) << '\n';
}

Output:

en_US: $1.23 or USD  1.23
ru_RU: 1.23 руб or 1.23 RUB 
ja_JP: ￥123 or JPY  123
