NAME¶

std::moneypunct - std::moneypunct

Synopsis¶

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.

Specializations¶

The standard library is guaranteed to provide the following specializations (they
are required to be implemented by any locale object):

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
