lconv
| Defined in header  <locale.h> | ||
| 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_signin a non-negative monetary value(public member object) | 
| char n_sign_posn | indicates the position of negative_signin 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_signin a non-negative international monetary value(public member object) | 
| char int_n_sign_posn | indicates the position of negative_signin 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 |
