Defined in header <locale>
template< class CharT, bool International = false > class moneypunct;

The facet std::moneypunct encapsulates monetary value format preferences. Stream I/O manipulators std::get_money and std::put_money use std::moneypunct through std::money_get and std::money_put for parsing monetary value input and formatting monetary value output.

Inheritance diagram

Four standalone (locale-independent) specializations are provided by the standard library:

Defined in header <locale>
std::moneypunct<char>	provides equivalents of the "C" locale preferences
std::moneypunct<wchar_t>	provides wide character equivalents of the "C" locale preferences
std::moneypunct<char, true>	provides equivalents of the "C" locale preferences, with international currency symbols
std::moneypunct<wchar_t, true>	provides wide character equivalents of the "C" locale preferences, with international currency symbols

In addition, every locale object constructed in a C++ program implements its own (locale-specific) versions of these specializations.

Member types

Member functions

(constructor)	constructs a new moneypunct facet (public member function)
(destructor)	destructs a moneypunct facet (protected member function)
decimal_point	invokes do_decimal_point (public member function)
thousands_sep	invokes do_thousands_sep (public member function)
grouping	invokes do_grouping (public member function)
curr_symbol	invokes do_curr_symbol (public member function)
positive_signnegative_sign	invokes do_positive_sign or do_negative_sign (public member function)
frac_digits	invokes do_frac_digits (public member function)
pos_formatneg_format	invokes do_pos_format/do_neg_format (public member function)

Protected member functions

do_decimal_point [virtual]	provides the character to use as decimal point (virtual protected member function)
do_thousands_sep [virtual]	provides the character to use as thousands separator (virtual protected member function)
do_grouping [virtual]	provides the numbers of digits between each pair of thousands separators (virtual protected member function)
do_curr_symbol [virtual]	provides the string to use as the currency identifier (virtual protected member function)
do_positive_signdo_negative_sign [virtual]	provides the string to indicate a positive or negative value (virtual protected member function)
do_frac_digits [virtual]	provides the number of digits to display after the decimal point (virtual protected member function)

Member objects

static std::locale::id id

id of the locale (public member object)

Inherited from std::money_base

Member type	Definition
enum part { none, space, symbol, sign, value };	unscoped enumeration type
struct pattern { char field[4]; };	the monetary format type

Enumeration constant	Definition
none	whitespace is permitted but not required except in the last position, where whitespace is not permitted
space	one or more whitespace characters are required
symbol	the sequence of characters returned by moneypunct::curr_symbol is required
sign	the first of the characters returned by moneypunct::positive_sign or moneypunct::negative_sign is required
value	the absolute numeric monetary value is required
