std::money_put: std::money_put

NAME

std::money_put - std::money_put

Synopsis


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 functions


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

Protected member functions


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

Member objects


                          id of the locale
static std::locale::id id (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.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 €
