std::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.

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.

[edit] 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 container 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.

#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';
}

American locale: 123,456ドル.79
German locale: 123.456,79 €
