localeconv

Description

array localeconv ( void )

Returns an associative array containing localized numeric and monetary formatting information.

localeconv() returns data based upon the current locale as set by setlocale(). The associative array that is returned contains the following fields:

Array element Description

decimal_point Decimal point character

thousands_sep Thousands separator

grouping Array containing numeric groupings

int_curr_symbol International currency symbol (i.e. USD)

currency_symbol Local currency symbol (i.e. $)

mon_decimal_point Monetary decimal point character

mon_thousands_sep Monetary thousands separator

mon_grouping Array containing monetary groupings

positive_sign Sign for positive values

negative_sign Sign for negative values

int_frac_digits International fractional digits

frac_digits Local fractional digits

p_cs_precedes TRUE if currency_symbol precedes a positive value, FALSE if it succeeds one

p_sep_by_space TRUE if a space separates currency_symbol from a positive value, FALSE otherwise

n_cs_precedes TRUE if currency_symbol precedes a negative value, FALSE if it succeeds one

n_sep_by_space TRUE if a space separates currency_symbol from a negative value, FALSE otherwise

p_sign_posn

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

n_sign_posn

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

The grouping fields contain arrays that define the way numbers should be grouped. For example, the grouping field for the en_US locale, would contain a 2 item array with the values 3 and 3. The higher the index in the array, the farther left the grouping is. If an array element is equal to CHAR_MAX, no further grouping is done. If an array element is equal to 0, the previous element should be used.
