Member functions
constructs a new moneypunct_byname facet (public member function) | |
destroys a moneypunct_byname facet (protected member function) |
std::moneypunct_byname::moneypunct_byname
explicit moneypunct_byname( const char* name, std::size_t refs = 0 );
|

explicit moneypunct_byname( const std::string& name, std::size_t refs = 0 );
|
(since C++11) | |
Constructs a new std::moneypunct_byname facet for a locale with name.
refs is used for resource management: if refs == 0, the implementation destroys the facet, when the last std::locale object holding it is destroyed. Otherwise, the object is not destroyed.
Parameters
| name | - | the name of the locale |
| refs | - | the number of references that link to the facet |
std::moneypunct_byname::~moneypunct_byname
protected:
~moneypunct_byname();
|
||
Destroys the facet.

the monetary format type |

none
|
whitespace is permitted but not required except in the last position, where whitespace is not permitted |
space
|
one or more whitespace characters are required |
symbol
|
the sequence of characters returned by std::moneypunct::curr_symbol is required |
sign
|
the first of the characters returned by std::moneypunct::positive_sign or std::moneypunct::negative_sign is required |
value
|
the absolute numeric monetary value is required |
Example
This example demonstrates how to apply monetary formatting rules of another language without changing the rest of the locale.
Run this code
#include <iomanip>
#include <iostream>
#include <locale>
int main()
{
long double mon = 1234567;
std::locale::global(std::locale("en_US.utf8"));
std::wcout.imbue(std::locale());
std::wcout << L"american locale: " << std::showbase
<< std::put_money(mon) << '\n';
std::wcout.imbue(std::locale(std::wcout.getloc(),
new std::moneypunct_byname<wchar_t>("ru_RU.utf8")));
std::wcout << L"american locale with russian moneypunct: "
<< std::put_money(mon) << '\n';
}
Output:
american locale: $12,345.67
american locale with russian moneypunct: 12 345.67 руб
