std::get_money

template< class MoneyT >
/*unspecified*/ get_money( MoneyT& mon, bool intl = false );

When used in an expression in >> get_money(mon, intl), parses the character input as a monetary value, as specified by the std::money_get facet of the locale currently imbued in in, and stores the value in mon.

The extraction operation in in >> get_money(mon, intl) behaves as a FormattedInputFunction.

Parameters

Return value

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

typedef std::istreambuf_iterator<CharT, Traits> Iter;
typedef std::money_get<CharT, Iter> MoneyGet;
std::ios_base::iostate err = std::ios_base::goodbit;
const MoneyGet &mg = std::use_facet<MoneyGet>(in.getloc());
mg.get(Iter(in.rdbuf()), Iter(), intl, in, err, mon);
if (std::ios_base::goodbit != err)
out.setstate(err);

Example

#include <iostream>
#include <sstream>
#include <locale>
#include <iomanip>
 
int main()
{
    std::istringstream in("$1,234.56 2.22 USD  3.33");
    long double v1, v2;
    std::string v3;
    in.imbue(std::locale("en_US.UTF-8"));
    in >> std::get_money(v1) >> std::get_money(v2) >> std::get_money(v3, true);
    if (in) {
        std::cout << std::quoted(in.str()) << " parsed as: "
                  << v1 << ", " << v2 << ", " << v3 << '\n';
    } else {
        std::cout << "Parse failed";
    }
}

"$1,234.56 2.22 USD  3.33" parsed as: 123456, 222, 333
