# std::money_get

From cppreference.com
< cpp‎ | locale

Defined in header `<locale>` |  |
template< class CharT, class InputIt = std::istreambuf_iterator<CharT> > class money_get; |  |

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.

Inheritance diagram

### 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

(constructor) | constructs a new money_get facet (public member function)
(destructor) | destructs a money_get facet (protected member function)
get | invokes `do_get` (public member function)

### Protected member functions

do_get [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

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
