The localeconv() function returns a pointer to a structure of type lconv, which contains a variety of geopolitical environmental information relating to the way numbers are formatted. The lconv structure contains the following members :
char *decimal_point; /* Decimal point character for nonmonetary values. */ char *thousands_sep; /* Thousands separator for nonmonetary values. */ char *grouping; /* Specifies grouping for nonmonetary values. */ char *int_curr_symbol; /* International currency symbol. */ char *currency_symbol; /* Local currency symbol. */ char *mon_decimal_point; /* Decimal point character for monetary values. */ char *mon_thousands_sep; /* Thousands separator for monetary values. */ char *mon_grouping; /* Specifies grouping for monetary values. */ char *positive_sign; /* Positive values indicator for monetary values. */ char *negative_sign; /* Negative value indicator for monetary values. */ char int_frac_digits; /* Number of digits displayed to the right of the decimal point for monetary values displayed using international format. */ char frac_digits; /* Number of digits displayed to the right of the decimal point for monetary values displayed using local format. */ char p_cs_precedes; /* 1 if currency symbol precedes positive value, 0 if currency symbol follows value. */ char p_sep_by_space; /* 1 if currency symbol is separated from value by a space, 0 otherwise. In C99, contains a value that indicates separation. */ char n_cs_precedes; /* 1 if currency symbol precedes a negative value, 0 if currency symbol follows value. */ char n_sep_by_space; /* 1 if currency symbol is separated from a negative value by a space, 0 if currency symbol follows value. In C99, contains a value that indicates separation. */ char p_sign_posn; /* Indicates position of positive value symbol. */ char n_sign_posn; /* Indicates position of negative value symbol. */ /* The following members were added by C99. */ char _p_cs_precedes; /* 1 if currency symbol precedes positive value, 0 if currency symbol follows value. Applies to internationally formatted values. */ char _p_sep_by_space; /* Indicates the separation between the currency symbol, sign, and a positive value. Applies to internationally formatted values. */ char _n_cs_precedes; /* 1 if currency symbol precedes a negative value, 0 if currency symbol follows value. Applies to internationally formatted values. */ char _n_sep_by_space; /* Indicates the separation between the currency symbol, sign, and a negative value. Applies to internationally formatted values. */ char _p_sign_posn; /* Indicates position of positive value symbol. Applies to internationally formatted values. */ char n_sign_posn; /* Indicates position of negative value symbol. Applies to internationally formatted values. */
The localeconv() function returns a pointer to the lconv structure. You must not alter the contents of this structure. Refer to your computer's documentation for implementation-specific information relating to the lconv structure.
Following is the syntax of the localeconv() function :
#include<locale.h> struct lconv *localeconv(void);
Following program displays the decimal point character used by the current locale :
#include<stdio.h>
#include<locale.h>
#include<conio.h>
void main()
{
clrscr();
struct lconv lc;
lc = *localeconv();
printf("Decimal symbol is: %s\n", lc.decimal_point);
getch();
}
