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 <iomanip>
#include <iostream>
#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 €
