std::get_money (3) - Linux Manuals

std::get_money: std::get_money


std::get_money - std::get_money


Defined in header <iomanip>
template< class MoneyT > (since C++11)
/*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.


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

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)


// Run this code

  #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 >> 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
