std::money_put(3) C++ Standard Libary std::money_put(3)


std::money_put - std::money_put


Defined in header <locale>

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.


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
std::money_put<wchar_t> creates wide string representations of monetary
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 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 formats a monetary value and writes to output stream
[virtual] (virtual protected member function)

Member objects

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


// Run this code

#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: " ;
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: $123,456.79
german locale: 123.456,79 €
