Class template std::money_get
encapsulates the rules for parsing monetary values from character streams. The standard I/O manipulator std::get_money uses the std::money_get
facet of the I/O stream's locale.

[edit] Specializations
Two standalone (locale-independent) full specializations and two partial specializations are provided by the standard library:
Defined in header
<locale> |
|
std::money_get<char> | parses narrow string representations of monetary values |
std::money_get<wchar_t> | parses wide string representations of monetary values |
std::money_get<char, InputIt> | parses narrow string representations of monetary values using custom input iterator |
std::money_get<wchar_t, InputIt> | parses wide string representations of monetary values using custom input iterator |
In addition, every locale object constructed in a C++ program implements its own (locale-specific) versions of these specializations.

[edit] Example
Run this code
#include <iostream> #include <sstream> #include <locale> #include <iomanip> #include <iterator> int main() { std::string str = "$1.11 $2.22 $3.33"; std::cout << std::fixed << std::setprecision(2); std::cout << '"' << str << "\" parsed with the I/O manipulator: "; std::istringstream s1(str); s1.imbue(std::locale("en_US.UTF-8")); long double val; while(s1 >> std::get_money(val)) std::cout << val/100 << ' '; std::cout << '\n'; str = "USD 1,234.56"; std::cout << '"' << str << "\" parsed with the facet directly: "; std::istringstream s2(str); s2.imbue(std::locale("en_US.UTF-8")); auto& f = std::use_facet<std::money_get<char>>(s2.getloc()); std::ios_base::iostate err; std::istreambuf_iterator<char> beg(s2), end; f.get(beg, end, true, s2, err, val); std::cout << val/100 << '\n'; }
Output:
"$1.11 $2.22 $3.33" parsed with the I/O manipulator: 1.11 2.22 3.33 "USD 1,234.56" parsed with the facet directly: 1234.56
