Formats a number
into a currency string (e.g., $13.65). You
can customize the format in the options
hash.
Options
-
:locale
- Sets the locale to be used for formatting (defaults to current locale). -
:precision
- Sets the level of precision (defaults to 2). -
:unit
- Sets the denomination of the currency (defaults to â$â). -
:separator
- Sets the separator between the units (defaults to â.â). -
:delimiter
- Sets the thousands delimiter (defaults to â,â). -
:format
- Sets the format for non-negative numbers (defaults to â%u%nâ). Fields are%u
for the currency, and%n
for the number. -
:negative_format
- Sets the format for negative numbers (defaults to prepending an hyphen to the formatted number given by:format
). Accepts the same fields than:format
, except%n
is here the absolute value of the number.
