NAME

       Locale::Currency::Format - Perl functions for formatting monetary values

SYNOPSIS

	 use Locale::Currency::Format;

	 $amt = currency_format('USD', 1000);		  # => 1,000.00 USD
	 $amt = currency_format('EUR', 1000, FMT_COMMON); # => EUR1.000,00
	 $amt = currency_format('USD', 1000, FMT_SYMBOL); # => $1,000.00

	 $sym = currency_symbol('USD'); 		  # => $
	 $sym = currency_symbol('GBP', SYM_HTML);	  # => £

	 $decimals = decimal_precision('USD');		  # => 2
	 $decimals = decimal_precision('BHD');		  # => 3

	 $thou_sep = thousands_separator('USD');	  # => ,
	 $thou_sep = thousands_separator('EUR');	  # => .

	 $dec_sep = decimal_separator('USD');		  # => .
	 $dec_sep = decimal_separator('EUR');		  # => ,

	 currency_set('USD', '#.###,## $', FMT_COMMON);   # => set custom format
	 currency_format('USD', 1000, FMT_COMMON);	  # => 1.000,00 $
	 currency_set('USD');				  # => reset default format

       The following example illustrates how to use Locale::Currency::Format with Mason. Skip it if you are not interested in Mason. A simple
       Mason component might look like this:

	 Total: <% 123456789, 'eur' |c %>

	 <%init>
	   use Locale::Currency::Format;

	   $m->interp->set_escape(c => &escape_currency);

	   sub escape_currency {
	     my ($amt, $code) = ${$_[0]} =~ /(.*?)([A-Za-z]{3})/;
	     ${$_[0]} = currency_format($code, $amt, FMT_HTML);
	   }
	 </%init>

DESCRIPTION

       Locale::Currency::Format is a light-weight Perl module that enables Perl code to display monetary values in the formats recognized
       internationally and/or locally.

       "currency_format(CODE, AMOUNT [, FORMAT])"
	 currency_format takes two mandatory parameters, namely currency code and amount respectively, and optionally a third parameter indicating
	 which format is desired. Upon failure, it returns undef and an error message is stored in $Locale::Currency::Format::error.

	     CODE
		 A 3-letter currency code as specified in ISO 4217.
		 Note that old code such as GBP, FRF and so on can also
		 be valid.

	     AMOUNT
		 A numeric value.

	     FORMAT
		 There are five different format options FMT_STANDARD,
		 FMT_COMMON, FMT_SYMBOL, FMT_HTML and FMT_NAME. If it is
		 omitted, the default format is FMT_STANDARD.

		 FMT_STANDARD Ex: 1,000.00 USD, 1.000.000,00 EUR
		 FMT_SYMBOL   Ex: $1,000.00
		 FMT_COMMON   Ex: 1.000 Dong (Vietnam), BEF 1.000 (Belgium)
		 FMT_HTML     Ex: &#xA3;1,000.00  (pound-sign HTML escape)
		 FMT_NAME     Ex: 1,000.00 US Dollar

		 NOTE: By default the trailing zeros after the decimal
		 point will be added. To turn it off, do a bitwise C<or>
		 of FMT_NOZEROS with one of the five options above.
		 Ex: FMT_STANDARD | FMT_NOZEROS  will give 1,000 USD

       "currency_symbol(CODE [, TYPE])"
	 For conveniences, the function currency_symbol is provided for currency symbol lookup given a 3-letter currency code. Optionally, one can
	 specify which format the symbol should be returned - Unicode-based character or HTML escape.  Default is a Unicode-based character. Upon
	 failure, it returns undef and an error message is stored in $Locale::Currency::Format::error.

	     CODE
		 A 3-letter currency code as specified in ISO 4217

	     TYPE
		 There are two available types SYM_UTF and SYM_HTML
		 SYM_UTF  returns the symbol (if exists) as an Unicode
			  character
		 SYM_HTML returns the symbol (if exists) as a HTML escape

       "decimal_precision(CODE)"
	 For conveniences, the function decimal_precision is provided to lookup the decimal precision for a given 3-letter currency code.

	 Upon failure, it returns undef and an error message is stored in $Locale::Currency::Format::error.

	     CODE
		 A 3-letter currency code as specified in ISO 4217

       "decimal_separator(CODE)"
	 For conveniences, the function decimal_separator is provided to lookup the decimal separator for a given 3-letter currency code.

	 Upon failure, it returns undef and an error message is stored in $Locale::Currency::Format::error.

	     CODE
		 A 3-letter currency code as specified in ISO 4217

       "thousands_separator(CODE)"
	 For conveniences, the function thousands_separator is provided to lookup the thousands separator for a given 3-letter currency code.

	 Upon failure, it returns undef and an error message is stored in $Locale::Currency::Format::error.

	     CODE
		 A 3-letter currency code as specified in ISO 4217

       "currency_set(CODE [, TEMPLATE, FORMAT])"
	 currency_set can be used to set a custom format for a currency instead of the provided format. For example, in many non-English speaking
	 countries, the US dollars might be displayed as 2.999,99 $ instead of the usual $2,999.99. In order to accomplish this, one will need to
	 do as follows:

	     use Locale::Currency::Format qw(:default $error);

	     my $currency = 'USD';
	     my $template = '#.###,## $';
	     if (currency_set($currency, $template, FMT_COMMON)) {
		 print currency_format($currency, 2999.99, FMT_COMMON), "
";
	     }
	     else {
		 print "cannot set currency format for $currency: $error
";
	     }

	 The arguments to currency_set are:

	     CODE
		 A 3-letter currency code as specified in ISO 4217

	     TEMPLATE
		 A template in the form #.###,##$, #.### kr, etc.

		 If a unicode character is used, make sure that
		 the template is double-quoted.
		 Ex: currency_set('GBP', "x{00A3}#,###.##", FMT_SYMBOL)

		 If an HTML symbol is wanted, escape its equivalent HTML code.
		 Ex: currency_set('GBP', '&#x00A3;#,###.##', FMT_HTML)

	     FORMAT
		 This argument is required if TEMPLATE is present.
		 The formats FMT_SYMBOL, FMT_COMMON, FMT_HTML are accepted.

		 NOTE!
		 FMT_STANDARD and FMT_NAME will always be in the form
		 <amount><space><code|name> such as 1,925.95 AUD. Hence,
		 currency_set returns an error if FMT_STANDARD or FMT_NAME
		 is specified as FORMAT.

		 With FMT_COMMON, you can always achieve what you would
		 have done with FMT_STANDARD and FMT_NAME, as follows

		 my $amt = 1950.95;
		 currency_set('USD', 'USD #.###,##', FMT_COMMON);
		 print currency_format('USD', $amt, FMT_COMMON); # USD 1,950.95
		 currency_set('USD', 'US Dollar #.###,##', FMT_COMMON);
		 print currency_format('USD', $amt, FMT_COMMON); # US Dollar 1,950.95

	 Invoking currency_set with one argument will reset all formats to their original settings.

	 For example

	     currency_set('USD')

	 will clear all previous custom settings for the US currency (ie. FMT_SYMBOL, FMT_HTML, FMT_COMMON).

   A WORD OF CAUTION
       Please be aware that some currencies might have missing common format. In that case, currency_format will fall back to FMT_STANDARD format.

       Also, be aware that some currencies do not have monetary symbol.

       As countries merge together or split into smaller ones, currencies can be added or removed by the ISO. Please help keep the list up to date
       by sending your feedback to the email address at the bottom.

       To see the error, examine $Locale::Currency::Format::error

	   use Locale::Currency::Format;
	   my $value = currency_format('USD', 1000);
	   print $value ? $value : $Locale::Currency::Format::error

	   OR

	   use Locale::Currency::Format qw(:DEFAULT $error);
	   my $value = currency_format('USD', 1000);
	   print $value ? $value : $error

       Lastly, please refer to perluniintro and perlunicode for displaying Unicode characters if you intend to use FMT_SYMBOL and currency_symbol.
       Otherwise, it reads "No worries, mate!"
