# std::moneypunct

From cppreference.com
< 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.

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
