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.
