# std::moneypunct::decimal_point, do_decimal_point

From cppreference.com
< cpp‎ | locale‎ | moneypunct

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'.')

### [edit] Return value

The object of type `CharT` holding the decimal point character.

### [edit] Example

Run this code

    #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 €
