};

decimal_point

Character string containing the non-monetary decimal point.

thousands_sep

Character string containing the non-monetary separator for digit grouping.

grouping

Non-monetary digit grouping sequence, encoded in a character string. Each character in the sequence is actually a number specifying the number of digits to group left of the decimal point. The null character, 0, specifies that the preceding group should be repeated. The number CHAR_MAX specifies that grouping is no longer required.

int_curr_symbol

Character string composed of a 3-character international currency symbol followed by separation character between the currency symbol and the currency number.

currency_symbol

Character string containing the local currency symbol.

mon_decimal_point

Character string containing the monetary decimal point.

mon_thousands_sep

Character string containing the monetary separator for digit grouping.

mon_grouping

Monetary digit grouping sequence. Uses same format as grouping.

positive_sign

Character string containing the sign for positive monetary numbers.

negative_sign

Character string containing the sign for negative monetary numbers.

int_frac_digits

Number of digits that may appear to the right of the decimal point for international monetary numbers.

frac_digits

Number of digits that may appear to the right of the decimal point for non-international monetary numbers.

p_cs_precedes

Contains 1 if currency_symbol should precede positive monetary numbers, 0 otherwise.

p_sep_by_space

Contains 1 if currency_symbol should be separated from positive monetary values by a space, 0 otherwise.

n_cs_precedes

Contains 1 if currency_symbol should precede negative monetary numbers, 0 otherwise.

n_sep_by_space

Contains 1 if currency_symbol should be separated from negative monetary values by a space, 0 otherwise.

p_sign_posn

Specifies how to use the positive_sign character string. Contains 0 when parentheses should surround the number and currency_symbol, 1 when the sign should precede the number and currency_symbol, 2 when the sign should follow the number and currency_symbol, 3 when the sign precedes currency_symbol, 4 when the sign follows currency_symbol.

n_sign_posn

Specifies how to use the negative_sign character string. Follows the same convention as p_sign_posn.

The lconv structure specifies numeric formatting requirements. Use localeconv() to retrieve a pointer to an lconv structure for the current locale.
