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

      From cppreference.com
      <cpp‎ |locale‎ |moneypunct
       
       
       
      Localization library
       
       
      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 functiondo_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, ifdo_frac_digits() is greater than zero). For typical U.S. locales, it is the character'.' (orL'.').

      [edit]Return value

      The object of typeCharT holding the decimal point character.

      [edit]Example

      Run this code
      #include <iomanip>#include <iostream>#include <locale> void show_dpt(constchar* 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: $1.23ja_JP.utf8 decimal point is '.' for example: ¥123 (does not use frac digits)sv_SE.utf8 decimal point is ',' for example: 1,23 krde_DE.utf8 decimal point is ',' for example: 1,23 €
