DESCRIPTION ^

Currency conversion module using XE.com's Universal Currency Converter (tm) site.

WARNING: Do not use this module for any commercial purposes, unless you have obtain an explicit license to use the service provided by XE.com. For further details please read the Terms and Conditions available at http://www.xe.com.

METHODS ^

new

Creates a new Finance::Currency::Convert::XE object. Can be supplied with default values for source and target currency, and the format required of the output. These can be overridden in the convert() method.

currencies

Returns a plain array of the currencies available for conversion.

add_currencies

Allows the user to add currencies to the internal hash. Currencies can be added as per the code below:

    $self->add_currencies(
                ZZZ => {text => 'An Example', symbol => '$'},
                ZZY => {text => 'Testing'} 
    );

Note that unless otherwise stated, the symbol will be set to '¤'. The code used must be 3 characters in length, and a text part must be included.

convert

Converts some currency value into another using XE.com's UCC.

An anonymous hash is used to pass parameters. Legal hash keys and values are as follows:

  convert(
    source => $currency_from,
    target => $currency_to,
    value  => $currency_from_value,
    format => $print_format
  );

The format key is optional, and takes one of the following strings:

  'number' (returns '12.34')
  'symbol' (returns '£12.34')
  'text'   (returns '12.34 Great Britain, Pound')
  'abbv'   (returns '12.34 GBP')

If format key is omitted, 'number' is assumed and the converted value is returned.

If only a value is passed, it is assumed that this is the value to be converted and the remaining parameters will be defined by the defaults set in the constructor. Note that no internal defaults are assumed.

Note that not all countries have symbols in the standard character set. Where known the appropriate currency symbol is used, otherwise the generic currency symbol is used.

It should also be noted that there is a recommendation to use only the standardised three letter abbreviation ('abbv' above). However, for further reading please see:

error

Returns a (hopefully) meaningful error string.
