std::moneypunct

< cpp‎ | locale

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.

Protected member functions

do_decimal_point [virtual]	provides the character to use as decimal point (virtual protected member function)

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

money_base	defines monetary formatting patterns (class)
moneypunct_byname	represents the system-supplied std::moneypunct for the named locale (class template)
money_get	parses and constructs a monetary value from an input character sequence (class template)
money_put	formats a monetary value for output as a character sequence (class template)
