1) Public member function, calls the member function
do_pos_format of the most derived class. 2) Public member function, calls the member function
do_neg_format of the most derived class. 3) Returns the format structure (of type
std::money_base::format) which describes the formatting of positive monetary values. 4) Returns the format structure (of type
std::money_base::format) which describes the formatting of negative monetary values.The standard specializations of std::moneypunct return the pattern {symbol, sign, none, value}
Return value
The object of type std::money_base::format describing the formatting used by this locale.
Example
#include <locale>
#include <iostream>
#include <iomanip>
struct my_punct : std::moneypunct_byname<char, false> {
my_punct(const char* name) : moneypunct_byname(name) {}
pattern do_pos_format() const { return { {value, space, symbol, sign} };}
pattern do_neg_format() const { return { {value, space, symbol, sign} };}
};
int main()
{
std::cout.imbue(std::locale("en_US.utf8"));
std::cout << "american locale: " << std::showbase
<< std::put_money(12345678.0) << '\n';
std::cout.imbue(std::locale(std::cout.getloc(), new my_punct("en_US.utf8")));
std::cout << "locale with modified moneypunct:\n"
<< std::put_money(12345678.0) << '\n'
<< std::put_money(-12345678.0) << '\n';
}Output:
american locale: $123,456.78 locale with modified moneypunct: 123,456.78 $ 123,456.78 $-
