std::moneypunct
From cppreference.com
| 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.
