When we test our currency converter it shows a weird number before the numbers we enter. "25 pounds to U.S. dollars" returns "$1.5406, 25 British Pound = $38.52 U.S. Dollar". (For the record, Google says "25 British pounds sterling = 38.5375 US dollars".) What's wrong?

* Currency conversion API function
*
* This function converts two currencies using exchange rates from Yahoo Finance.
* The currency codes are standard ISO 3-letter codes, and you can find the details
* here:
* http://www.oanda.com/site/help/iso_code.shtml
*
* Here is an example on how to use it:
*
* $from = 'CAD';
* $to = 'USD';
* $amt = 20;
* $ret = currency_exchange($from, $to, $amt);
* if ($ret['status'] == FALSE)
* {
* drupal_set_message(t('An error occured: '). $ret['message']);
* }
* else
* {
* print $amt .' '. $from .' = '. $ret['value'];
* }
*
* @param $currency_from
* Currency to convert from
*
* @param $currency_to
* Currency to convert to
*
* @param $amount
* Option amount to convert. If not supplied, 1 is assumed.
*
* @return $result
* An associative array that contains the following:
* $result['status'] TRUE or FALSE
* $result['message']'success' when status is TRUE, otherwise, contains a
* descriptive error text
* The following items are only returned when status is TRUE
* $result['value'] $amount * exchange rate of $currency_from into $currency_to
* $result['date'] Date of the last update to the rates (Format is "m/d/yyyy")
* $result['time'] Time of the last update to the rates (Format is "h:mmpm")
