Defined in header <iomanip>
template< class MoneyT > /*unspecified*/ put_money( const MoneyT& mon, bool intl = false );		(since C++11)

When used in an expression out << put_money(mon, intl), converts the monetary value mon to its character representation as specified by the std::money_put facet of the locale currently imbued in out.

This function behaves as a FormattedOutputFunction

Parameters

mon	-	a monetary value, either long double or basic_string
intl	-	use international currency strings if true, use currency symbols otherwise

Return value

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);

Example

Run this code

#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
