public function formatPrecision($price, $precision,
$options=array(), $includeContainer = true, $addBrackets = false)

       if (!isset($options['precision'])) {

           $options['precision'] = $precision;

       }

       if ($includeContainer) {

           return '<span class="price">' . ($addBrackets ? '[' :
'') . $this->formatTxt($price, $options) . ($addBrackets ? ']' : '') .
