std::moneypunct_byname
is a
std::moneypunct
facet which encapsulates monetary formatting preferences of a locale specified at its construction.
Specializations
The standard library is guaranteed to provide every specialization that satisfies the following type requirements:
-
CharTis one of char and wchar_t , and -
Intlis a possible specialization on a bool parameter.

(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.

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.
#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
