NAME

std::moneypunct::decimal_point,do_decimal_point - std::moneypunct::decimal_point,do_decimal_point

Synopsis

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

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

// 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 €
