std::money_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.

Type requirements

-OutputIt must meet the requirements of LegacyOutputIterator.

Specializations

Two standalone (locale-independent) full specializations and two partial specializations are provided by the standard library:

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

In addition, every locale object constructed in a C++ program implements its own (locale-specific) versions of these specializations.

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

#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.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';
}

Output:

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

moneypunct	defines monetary formatting parameters used by `std::money_get` and `std::money_put` (class template)
money_get	parses and constructs a monetary value from an input character sequence (class template)
put_money (C++11)	formats and outputs a monetary value (function template)
