std::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.

The characters of the C-strings pointed to by grouping and mon_grouping are interpreted according to their numeric values. When the terminating '0円' 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円".

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:

0 no space separates the currency symbol and the value

1 sign sticks to the currency symbol, value is separated by a space

2 sign sticks to the value. Currency symbol is separated by a space

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

0 parentheses around the value and the currency symbol are used to represent the sign

1 sign before the value and the currency symbol

2 sign after the value and the currency symbol

3 sign before the currency symbol

4 sign after the currency symbol

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";
