NAME¶

std::money_get - std::money_get

Synopsis¶

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.

Type requirements¶

-
InputIt must meet the requirements of LegacyInputIterator.

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 parses a monetary value from an input stream
[virtual] (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
