=head1 NAME
Locale::Currency::Format - Perl functions for formatting monetary values
=head1 SYNOPSIS
use Locale::Currency::Format;
$amnt = currency_format('usd', 1000); # => 1,000.00 USD
$amnt = currency_format('eur', 1000, FMT_COMMON); # => EUR1.000,00
$amnt = currency_format('usd', 1000, FMT_SYMBOL); # => $1,000.00
$sym = currency_symbol('usd'); # => $
$sym = currency_symbol('gbp', SYM_HTML); # => £
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;
$m->interp->set_escape(c => \&escape_currency);
sub escape_currency {
my ($amnt, $code) = ${$_[0]} =~ /(.*?)([A-Za-z]{3})/;
${$_[0]} = currency_format($code, $amnt, FMT_HTML);
}
</%init>
=head1 DESCRIPTION
B<Locale::Currency::Format> is a light-weight Perl module that allows one
to display monetary values in the formats recognized internationally or
locally depending on his wish.
=over 2
=item C<currency_format(CODE, AMOUNT [, FORMAT])>
B<currency_format> takes two mandatory parameters, namely currency code and
amount respectively, and optionally a third parameter indicating which
format is desired. Upon failure, it returns I<undef> and an error message is
stored in B<$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
FMT_SYMBOL Ex: $1,000.00
FMT_COMMON Ex: 1.000 Dong (Vietnam), BEF 1.000 (Belgium)
FMT_HTML Ex: £1,000.00 (pound-sign HTML escape)
FMT_NAME Ex: 1,000.00 US Dollar
By default the trailing zeros after the decimal point will
be added. To turn it off, do a bitwise B<or> of FMT_NOZEROS
with one of the five options above.
Ex: FMT_STANDARD | FMT_NOZEROS will give 1,000 USD
=item C<currency_symbol(CODE [, TYPE])>
For conveniences, the function B<currency_symbol> is provided for symbol
lookup given a 3-letter currency code. Optionally, one can specify which
format the symbol should be returned - Unicode-based character or HTML escape.
Default is a Unicode-based character. Upon failure, it returns I<undef> and an error message is stored in B<$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
=head2 A WORD OF CAUTION
Please be aware that some currencies might have missing common format. In that case, B<currency_format> will fall back to B<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('US', 1000);
print $value ? $value : $Locale::Currency::Format::error
OR
use Locale::Currency::Format qw(:DEFAULT $error);
my $value = currency_format('US', 1000);
print $value ? $value : $error
Lastly, please refer to L<perluniintro> and L<perlunicode> for displaying Unicode characters if you intend to use B<FMT_SYMBOL> and B<currency_symbol>. Otherwise, it reads "No worries, mate!"
