Member functions

money_put::put money_put::do_put

 

Defined in header <locale>
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

Type requirements

- InputIt must meet the requirements of InputIterator.

Specializations

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

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

Protected member functions

do_put [virtual]	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)

Example

run this code

#include <iostream>
#include <locale>
#include <iomanip>
#include <iterator>
int main()
{
    // using the IO 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"));
    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';
}

Output:

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