template< class MoneyT > /*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.
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 |
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);
#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"; } }
Output:
"$1,234.56 2.22 USD 3.33" parsed as: 123456, 222, 333
