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.

InputIt must meet the requirements of InputIterator . |
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 type | Definition |
---|---|
char_type | CharT |
string_type | std::basic_string<CharT> |
iter_type | OutputIt |
constructs a new money_put facet (public member function) |
|
destructs a money_put facet (protected member function) |
|
invokes do_put (public member function) |
[virtual]
| formats a monetary value and writes to output stream (virtual protected member function) |
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.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
