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:
CHARMAX 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 4217:1987 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.

USAGE
The following table illustrates the rules used by four countries to
format monetary quantities.
Country Positive format Negative format International format
Italy L.1.234 -L.1.234 ITL.1.234
Netherlands F 1.234,56 F -1.234,56 NLG 1.234,56
