NAME
localeconv - get numeric formatting information
SYNOPSIS
#include <locale.h>
struct lconv *localeconv (void);
DESCRIPTION
localeconv sets the components of an object with type struct
lconv (defined in locale.h) with the values appropriate for
the formatting of numeric quantities (monetary and other-
wise) according to the rules of the current locale [see
setlocale(3C)]. The definition of struct lconv is given
below (the values for the fields in the C locale are given
in comments):
char *decimal_point; /* "." */
char *thousands_sep; /* "" (zero length string) */
char *grouping; /* "" */
char *int_curr_symbol; /* "" */
char *currency_symbol; /* "" */
char *mon_decimal_point; /* "" */
char *mon_thousands_sep; /* "" */
char *mon_grouping; /* "" */
char *positive_sign; /* "" */
char *negative_sign; /* "" */
char int_frac_digits; /* CHAR_MAX */
char frac_digits; /* CHAR_MAX */
char p_cs_precedes; /* CHAR_MAX */
char p_sep_by_space; /* CHAR_MAX */
char n_cs_precedes; /* CHAR_MAX */
char n_sep_by_space; /* CHAR_MAX */
char p_sign_posn; /* CHAR_MAX */
char n_sign_posn; /* CHAR_MAX */
The members of the structure with type char * are strings,
any of which (except decimal_point) can point to "", to
indicate that the value is not available in the current
locale or is of zero length. The members with type char are
nonnegative numbers, any of which can be CHAR_MAX (defined
in the limits.h header file) to indicate that the value is
not available in the current locale. The members are the
following:
char *decimal_point
The decimal-point character used to format non-monetary
quantities.
char *thousands_sep
The character used to separate groups of digits to the
left of the decimal-point character in formatted non-

monetary quantities.
char *grouping
A string in which each element is taken as an integer
that indicates the number of digits that comprise the
current group in a formatted non-monetary quantity.
The elements of grouping are interpreted according to
the following:
CHAR-MAX No further grouping is to be per-
formed.
0 The previous element is to be repeat-
edly used for the remainder of the
digits.
other The value is the number of digits that
comprise the current group. The next
element is examined to determine the
size of the next group of digits to
the left of the current group.
char *int_curr_symbol
The international currency symbol applicable to the
current locale, left-justified within a four-
character space-padded field. The character
sequences should match with those specified in: ISO
4217 Codes for the Representation of Currency and
Funds.
char *currency_symbol
The local currency symbol applicable to the current
locale.
char *mon_decimal_point
The decimal point used to format monetary quantities.
char *mon_thousands_sep
The separator for groups of digits to the left of the
decimal point in formatted monetary quantities.
char *mon_grouping
A string in which each element is taken as an integer
that indicates the number of digits that comprise the
current group in a formatted monetary quantity. The
elements of mon_grouping are interpreted according to
the rules described under grouping.
char *positive_sign
The string used to indicate a nonnegative-valued for-
matted monetary quantity.

char *negative_sign
The string used to indicate a negative-valued format-
ted monetary quantity.
char int_frac_digits
The number of fractional digits (those to the right
of the decimal point) to be displayed in an interna-
tionally formatted monetary quantity.
char frac_digits
The number of fractional digits (those to the right
of the decimal point) to be displayed in a formatted
monetary quantity.
char p_cs_precedes
Set to 1 or 0 if the currency_symbol respectively
precedes or succeeds the value for a nonnegative for-
matted monetary quantity.
char p_sep_by_space
Set to 1 or 0 if the currency_symbol respectively is
or is not separated by a space from the value for a
nonnegative formatted monetary quantity.
char n_cs_precedes
Set to 1 or 0 if the currency_symbol respectively
precedes or succeeds the value for a negative format-
ted monetary quantity.
char n_sep_by_space
Set to 1 or 0 if the currency_symbol respectively is
or is not separated by a space from the value for a
negative formatted monetary quantity.
char p_sign_posn
Set to a value indicating the positioning of the
positive_sign for a nonnegative formatted monetary
quantity. The value of p_sign_posn is interpreted
according to the following:
0 Parentheses surround the quantity and
currency_symbol.
1 The sign string precedes the quantity and
currency_symbol.
2 The sign string succeeds the quantity and
currency_symbol.
3 The sign string immediately precedes the
currency_symbol.

4 The sign string immediately succeeds the
currency_symbol.
char n_sign_posn
Set to a value indicating the positioning of the
negative_sign for a negative formatted monetary quan-
tity. The value of n_sign_posn is interpreted
according to the rules described under p_sign_posn.
RETURNS
localeconv returns a pointer to the filled-in object. The
structure pointed to by the return value may be overwritten
by a subsequent call to localeconv.
EXAMPLES
The following table illustrates the rules used by four coun-
tries to format monetary quantities.
