I'm trying to increase the allowed decimal places for displayed product prices to four.
Following the developer documentation, I have tried decorating AView and modifying the function formatPrice(). I have also tried decorating Math and modifying the $precision values. Both attempts have been unsuccessful, and did not effect the default business logic in any way.

<?php
// vim: set ts=4 sw=4 sts=4 et:

namespace Developer\FormatDisplayPrice\View;

/**
 * Abstract widget
 */
abstract class AView extends \XLite\View\AView implements \XLite\Base\IDecorator 
{
    /**
     * Format price
     *
     * @param float                 $value        Price
     * @param \XLite\Model\Currency $currency     Currency OPTIONAL
     * @param boolean               $strictFormat Flag if the price format is strict (trailing zeroes and so on options)
     *
     * @return string
     */
    public static function formatPrice($value, \XLite\Model\Currency $currency = null, $strictFormat = false)
    {
        if (null === $currency) {
            $currency = \XLite::getInstance()->getCurrency();
        }

        if ($currency->getRoundUp() !== \XLite\Model\Currency::ROUNDUP_NONE && !\XLite::isAdminZone()) {
            $pow   = pow(10, (int) $currency->getRoundUp());
            $value = ceil($value * $pow) / $pow;
        }

        $parts = $currency->formatParts($value);

        if (isset($parts['sign']) && '-' === $parts['sign']) {
            $parts['sign'] = '− ';
        }

        if ($strictFormat) {
            $parts = static::formatPartsStrictly($parts);
        }

        /*
         * initial test
         * return unformatted prices
         */
        return $value;
    }
}

Do these classes need to be decorated in a different manner?
Am I decorating the correct classes and/or functions for this problem?

Any help or guidance is appreciated.
