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.

Type requirements

InputIt must meet the requirements of InputIterator.


Two specializations and two partial specializations are provided by the standard library and are implemented by all locale objects created in a C++ program:

Defined in header <locale>
std::money_put<char> creates narrow string representations of monetary values
std::money_put<wchar_t> creates wide string representations of monetary values
std::money_put<char, OutputIt> creates narrow string representations of monetary values using custom output iterator
std::money_put<wchar_t, OutputIt> creates wide string representations of monetary values using custom output iterator

Member types

Member type Definition
char_type CharT
string_type std::basic_string<CharT>
iter_type OutputIt

Member functions

constructs a new money_put facet
(public member function)
destructs a money_put facet
(protected member function)
invokes do_put
(public member function)

Protected member functions

formats a monetary value and writes to output stream
(virtual protected member function)

Member objects

static std::locale::id id
id of the locale
(public member object)


#include <iostream>
#include <locale>
#include <iomanip>
#include <iterator>
int main()
    // using the IO manipulator
    std::cout << "american locale: "
               << std::showbase << std::put_money(12345678.9)<< '\n';
    // using the facet directly
    std::cout << "german locale: " ;
    std::ostreambuf_iterator<char> out(std::cout);
    auto& f = std::use_facet<std::money_put<char>>(std::cout.getloc());
    f.put(out, false, std::cout, std::cout.fill(), 12345678.9 );
    std::cout << '\n';


american locale: $123,456.79
german locale: 123.456,79 EUR
