std::money_put

template< 
    class CharT,
    class OutputIt = std::ostreambuf_iterator<CharT>
> 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.

Inheritance diagram.

If a std::money_put specialization is not guaranteed to be provided by the standard library (see below), the behaviors of its put() and do_put() are not guaranteed as specified.

Specializations

The standard library is guaranteed to provide the following specializations (they are required to be implemented by any locale object):

In addition, the standard library is also guaranteed to provide every specialization that satisfies the following type requirements:

• CharT is one of
  • char,
  • wchar_t, and
  • any other implementation-defined character type that meets the requirements for a character on which any of the iostream components can be instantiated; and
• OutputIt must meet the requirements of LegacyOutputIterator.

Example

#include <iomanip>
#include <iostream>
#include <iterator>
#include <locale>
 
int main()
{
    // using the I/O manipulator
    std::cout.imbue(std::locale("en_US.UTF-8"));
    std::cout << "American locale: "
               << std::showbase << std::put_money(12345678.9) << '\n';
 
    // using the facet directly
    std::cout.imbue(std::locale("de_DE.UTF-8"));
    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';
}
