/*unspecified*/ get_money( MoneyT& mon, bool intl = false );
(since C++11)

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.


[edit] Parameters

mon - variable where monetary value will be written. Can be either long double or std::basic_string
intl - expects to find required international currency strings if true, expects optional currency symbols otherwise

[edit] Return value

An object of unspecified type such that

  • if in is an object of type std::basic_istream<CharT, Traits>, the expression in >> get_money(mon, intl)
    • has type std::basic_istream<CharT, Traits>&
    • has value in
    • behaves as if it called f(in, mon, intl)

where the function f is defined as:

template<class CharT, class Traits, class MoneyT>
void f(std::basic_ios<CharT, Traits>& str, MoneyT& mon, bool intl)
    using Iter = std::istreambuf_iterator<CharT, Traits>;
    using MoneyGet = std::money_get<CharT, Iter>;
    std::ios_base::iostate err = std::ios_base::goodbit;
    const MoneyGet& mg = std::use_facet<MoneyGet>(str.getloc());
    mg.get(Iter(str.rdbuf()), Iter(), intl, str, err, mon);
    if (err != std::ios_base::goodbit)

[edit] Example

#include <iomanip>
#include <iostream>
#include <locale>
#include <sstream>
int main()
    std::istringstream in("$1,234.56 2.22 USD  3.33");
    long double v1, v2;
    std::string v3;
    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';
        std::cout << "Parse failed";


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