struct lconv;

The struct lconv
contains numeric and monetary formatting rules as defined by a C locale. Objects of this struct may be obtained with localeconv. The members of 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.

[edit] Member objects
[edit] Non-monetary numeric formatting parameters
char* decimal_point |
the character used as the decimal point (public member object) |
char* thousands_sep |
the character used to separate groups of digits before the decimal point (public member object) |
char* grouping |
a string whose elements indicate the sizes of digit groups (public member object) |
[edit] Monetary numeric formatting parameters
char* mon_decimal_point |
the character used as the decimal point (public member object) |
char* mon_thousands_sep |
the character used to separate groups of digits before the decimal point (public member object) |
char* mon_grouping |
a string whose elements indicate the sizes of digit groups (public member object) |
char* positive_sign |
a string used to indicate non-negative monetary quantity (public member object) |
char* negative_sign |
a string used to indicate negative monetary quantity (public member object) |
[edit] Local monetary numeric formatting parameters
char* currency_symbol |
the symbol used for currency in the current C locale (public member object) |
char frac_digits |
the number of digits after the decimal point to display in a monetary quantity (public member object) |
char p_cs_precedes |
1 if currency_symbol is placed before non-negative value, 0 if after (public member object) |
char n_cs_precedes |
1 if currency_symbol is placed before negative value, 0 if after (public member object) |
char p_sep_by_space |
indicates the separation of currency_symbol , positive_sign , and the non-negative monetary value (public member object) |
char n_sep_by_space |
indicates the separation of currency_symbol , negative_sign , and the negative monetary value (public member object) |
char p_sign_posn |
indicates the position of positive_sign in a non-negative monetary value (public member object) |
char n_sign_posn |
indicates the position of negative_sign in a negative monetary value (public member object) |
[edit] International monetary numeric formatting parameters
char* int_curr_symbol |
the string used as international currency name in the current C locale (public member object) |
char int_frac_digits |
the number of digits after the decimal point to display in an international monetary quantity (public member object) |
char int_p_cs_precedes |
1 if currency_symbol is placed before non-negative international monetary value, 0 if after (public member object) |
char int_n_cs_precedes |
1 if currency_symbol is placed before negative international monetary value, 0 if after (public member object) |
char int_p_sep_by_space |
indicates the separation of currency_symbol , positive_sign , and the non-negative international monetary value (public member object) |
char int_n_sep_by_space |
indicates the separation of currency_symbol , negative_sign , and the negative international monetary value (public member object) |
char int_p_sign_posn |
indicates the position of positive_sign in a non-negative international monetary value (public member object) |
char int_n_sign_posn |
indicates the position of negative_sign in a negative international monetary value (public member object) |
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:
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 |
