std::moneypunct<CharT,International>::decimal_point, do_decimal_point

Defined in header `<locale>`
public: CharT decimal_point() const;	(1)
protected: virtual CharT do_decimal_point() const;	(2)

1) Public member function, calls the member function do_decimal_point of the most derived class.

2) Returns the character to use as the decimal point separator in monetary I/O if the format uses fractions (that is, if do_frac_digits() is greater than zero). For typical U.S. locales, it is the character '.' (or L'.')

Return value

The object of type CharT holding the decimal point character.

Example

#include <iostream>
#include <iomanip>
#include <locale>
 
void show_dpt(const char* locname)
{
    std::locale loc(locname);
    std::cout.imbue(loc);
    std::cout << locname << " decimal point is '"
              << std::use_facet<std::moneypunct<char>>(loc).decimal_point()
              << "' for example: " << std::showbase << std::put_money(123);
    if (std::use_facet<std::moneypunct<char>>(loc).frac_digits() == 0)
        std::cout << " (does not use frac digits) ";
 
    std::cout << '\n';
}
 
int main()
{
    show_dpt("en_US.utf8");
    show_dpt("ja_JP.utf8");
    show_dpt("sv_SE.utf8");
    show_dpt("de_DE.utf8");
 
}

Output:

en_US.utf8 decimal point is '.' for example: $1.23
ja_JP.utf8 decimal point is '.' for example: ￥123 (does not use frac digits)
sv_SE.utf8 decimal point is ',' for example: 1,23 kr
de_DE.utf8 decimal point is ',' for example: 1,23 €
