Defined in header <locale>
template< class CharT, bool Intl = false > class moneypunct_byname : public std::moneypunct<CharT, Intl>;

std::moneypunct_byname is a std::moneypunct facet which encapsulates monetary formatting preferences of a locale specified at its construction.

Two specializations are provided by the standard library

Defined in header <locale>
std::moneypunct_byname<char, Intl>	locale-specific std::moneypunct facet for narrow character I/O
std::moneypunct_byname<wchar_t, Intl>	locale-specific std::moneypunct facet for wide character I/O

Member types

Member type	Definition
pattern	std::money_base::pattern
string_type	std::basic_string<CharT>

Member functions

(constructor)	constructs a new moneypunct_byname facet (public member function)
(destructor)	destructs a moneypunct_byname facet (protected member function)

Example

This example demonistrates how to apply monetary formatting rules of another language without changing the rest of the locale.

run this code

#include <iostream>
#include <iomanip>
#include <locale>
int main()
{
    long double mon = 1234567;
    std::locale::global(std::locale("en_US.utf8"));
    std::wcout.imbue(std::locale());
    std::wcout << L"american locale : " << std::showbase
               << std::put_money(mon) << '\n';
    std::wcout.imbue(std::locale(std::wcout.getloc(),
                                 new std::moneypunct_byname<wchar_t>("ru_RU.utf8")));
    std::wcout << L"american locale with russian moneypunct: "
               << std::put_money(mon) << '\n';
}

Output:

american locale : $12,345.67
american locale with russian moneypunct: 12 345.67 руб
