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

NAME

std::put_money - std::put_money

Synopsis


Defined in header <iomanip>
template< class MoneyT > (since C++11)
/*unspecified*/ put_money( const MoneyT& mon, bool intl = false );


When used in an expression out << put_money(mon, intl), converts the monetary value
mon to its character representation as specified by the std::money_put facet of the
locale currently imbued in out.


The insertion operation in out << put_money(mon, intl) behaves as a
FormattedOutputFunction.

Parameters


mon - a monetary value, either long double or std::basic_string
intl - use international currency strings if true, use currency symbols otherwise

Return value


Returns an object of unspecified type such that if out is the name of an output
stream of type std::basic_ostream<CharT, Traits>, then the expression out <<
put_money(mon, intl) behaves as if the following code was executed:


typedef std::ostreambuf_iterator<CharT, Traits> Iter;
typedef std::money_put<CharT, Iter> MoneyPut;
const MoneyPut& mp = std::use_facet<MoneyPut>(out.getloc());
const Iter end = mp.put(Iter(out.rdbuf()), intl, out, out.fill(), mon);
if (end.failed())
out.setstate(std::ios::badbit);

Example

// Run this code


#include <iostream>
#include <iomanip>


int main()
{
long double mon = 123.45; // or std::string mon = "123.45";


std::cout.imbue(std::locale("en_US.UTF-8"));
std::cout << std::showbase
<< "en_US: " << std::put_money(mon)
<< " or " << std::put_money(mon, true) << '\n';


std::cout.imbue(std::locale("ru_RU.UTF-8"));
std::cout << "ru_RU: " << std::put_money(mon)
<< " or " << std::put_money(mon, true) << '\n';


std::cout.imbue(std::locale("ja_JP.UTF-8"));
std::cout << "ja_JP: " << std::put_money(mon)
<< " or " << std::put_money(mon, true) << '\n';
}

Possible output:


en_US: $1.23 or USD 1.23
ru_RU: 1.23 руб or 1.23 RUB
ja_JP: ¥123 or JPY 123
