std::lconv

struct lconv;

The class std::lconv contains numeric and monetary formatting rules as defined by a C locale. Objects of this struct may be obtained with std::localeconv. The members of std::lconv are values of type char and of type char*. Each char* member except decimal_point may be pointing at a null character (that is, at an empty C-string). The members of type char are all non-negative numbers, any of which may be CHAR_MAX if the corresponding value is not available in the current C locale.

International monetary numeric formatting parameters

The characters of the C-strings pointed to by grouping and mon_grouping are interpreted according to their numeric values. When the terminating '\0' is encountered, the last value seen is assumed to repeat for the remainder of digits. If CHAR_MAX is encountered, no further digits are grouped. the typical grouping of three digits at a time is "\003".

The values of p_sep_by_space, n_sep_by_space, int_p_sep_by_space, int_n_sep_by_space are interpreted as follows:

The values of p_sign_posn, n_sign_posn, int_p_sign_posn, int_n_sign_posn are interpreted as follows:

Example

#include <clocale>
#include <iostream>
 
int main()
{
    std::setlocale(LC_ALL, "ja_JP.UTF-8");
    std::lconv* lc = std::localeconv();
    std::cout << "Japanese currency symbol: " << lc->currency_symbol
              << '(' << lc->int_curr_symbol << ")\n";
}

Japanese currency symbol: ￥(JPY )
