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 otherwise) 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 *decimalpoint; /* "." */
char *thousandssep; /* "" (zero length string) */
char *grouping; /* "" */
char *intcurrsymbol; /* "" */
char *currencysymbol; /* "" */
char *mondecimalpoint; /* "" */
char *monthousandssep; /* "" */
char *mongrouping; /* "" */
char *positivesign; /* "" */
char *negativesign; /* "" */
char intfracdigits; /* CHARMAX */
char fracdigits; /* CHARMAX */
char pcsprecedes; /* CHARMAX */
char psepbyspace; /* CHARMAX */
char ncsprecedes; /* CHARMAX */
char nsepbyspace; /* CHARMAX */
char psignposn; /* CHARMAX */
char nsignposn; /* CHARMAX */
The members of the structure with type char * are strings, any of which
(except decimalpoint) 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 CHARMAX (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 *decimalpoint
The decimal-point character used to format non-monetary quantities.
char *thousandssep
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 performed.
0 The previous element is to be repeatedly 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 *intcurrsymbol
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 *currencysymbol
The local currency symbol applicable to the current locale.
char *mondecimalpoint
The decimal point used to format monetary quantities.
char *monthousandssep
The separator for groups of digits to the left of the decimal
point in formatted monetary quantities.
char *mongrouping
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 mongrouping are
interpreted according to the rules described under grouping.
char *positivesign
The string used to indicate a nonnegative-valued formatted
monetary quantity.
char *negativesign
The string used to indicate a negative-valued formatted monetary
quantity.
char intfracdigits
The number of fractional digits (those to the right of the decimal
point) to be displayed in an internationally formatted monetary
quantity.
char fracdigits
The number of fractional digits (those to the right of the decimal
point) to be displayed in a formatted monetary quantity.

char pcsprecedes
Set to 1 or 0 if the currencysymbol respectively precedes or
succeeds the value for a nonnegative formatted monetary quantity.
char psepbyspace
Set to 1 or 0 if the currencysymbol respectively is or is not
separated by a space from the value for a nonnegative formatted
monetary quantity.
char ncsprecedes
Set to 1 or 0 if the currencysymbol respectively precedes or
succeeds the value for a negative formatted monetary quantity.
char nsepbyspace
Set to 1 or 0 if the currencysymbol respectively is or is not
separated by a space from the value for a negative formatted
monetary quantity.
char psignposn
Set to a value indicating the positioning of the positivesign for
a nonnegative formatted monetary quantity. The value of
psignposn is interpreted according to the following:
0 Parentheses surround the quantity and currencysymbol.
1 The sign string precedes the quantity and currencysymbol.
2 The sign string succeeds the quantity and currencysymbol.
3 The sign string immediately precedes the currencysymbol.
4 The sign string immediately succeeds the currencysymbol.
char nsignposn
Set to a value indicating the positioning of the negativesign for
a negative formatted monetary quantity. The value of nsignposn
is interpreted according to the rules described under psignposn.
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 countries to
format monetary quantities.
