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.

Type requirements
- InputIt must meet the requirements of InputIterator . |
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.
Member types
Member type | Definition |
---|---|
char_type | CharT |
string_type | std::basic_string<CharT> |
iter_type | InputIt |
Member functions
constructs a new money_get facet (public member function) | |
(destructor)
| destructs a money_get facet (protected member function) |
invokes do_get (public member function) |
Protected member functions
[virtual] | parses a monetary value from an input stream (virtual protected member function) |
Member objects
static std::locale::id id | id of the locale (public member object) |
Example
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 | #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 2 | "$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 |
