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.
[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 valueAn object of unspecified type such that
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)
str.setstate(err);
}[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.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[edit] See also parses and constructs a monetary value from an input character sequence
