| 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.

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 |
