DESCRIPTION

Localized currency formatter using the Unicode Common Locale Data Repository (CLDR).

Methods

format

Accepts a number and returns a formatted currency value as a character string, using the currency from the currency_code attribute and localized for the current locale.

Attributes

The common attributes locale, default_locale, numbering_system, decimal_sign, group_sign, plus_sign, minus_sign, and cldr_version are described under common attributes in CLDR::Number. All attributes described here other than currency_code and cash have defaults that change depending on the current locale. The attributes currency_sign, minimum_fraction_digits, maximum_fraction_digits, and rounding_increment also change depending on the currency_code and cash values. All string attributes are expected to be character strings, not byte strings.

currency_code

Default: none

Valid: ISO 4217 3-letter alphabetic currency codes

Examples: EUR (Euro), USD (US Dollar), JPY (Japanese Yen)

The currency code is case-insensitive and is required in order to call the format method, but not required to instantiate this formatter object.

currency_sign

Default: based on both locale and currency_code

Examples: US$ for root, en-CA with USD; $ for en, de with USD; $US for fr with USD; USD for es-MX with USD

cash

Default: false (0)

Formatting for cash can be different for some currencies. Setting cash to true (1) enables cash formatting when different from standard formatting.

pattern

Examples: ¤ #,##0.00 for root; ¤#,##0.00 for en; #,##0.00 ¤ for de, fr; ¤ #,##0.00;¤ -#,##0.00 for nl; and many other variations for different locales

minimum_integer_digits

Examples: 1 for all locales

minimum_fraction_digits

Examples: 2 for most currencies; 3 for BHD; 0 for JPY or for TWD when cash is true

maximum_fraction_digits

Examples: 2 for most currencies; 3 for BHD; 0 for JPY or for TWD when cash is true

primary_grouping_size

Examples: 3 for root and almost all locales

Not used when value is 0.

secondary_grouping_size

Examples: 0 for root, en, and most locales; 2 for hi, bn, en-IN, and other locales of the Indian subcontinent

Not used when value is 0.

rounding_increment

Examples: 0 for all currencies; 5 for CAD, CHF when cash is true

0 and 1 are treated the same.
