If you wand to display price with/without decimal points
here is the solution
$currency_code = Mage::app()->getStore()->getCurrentCurrencyCode();
echo $currency->formatPrecision(PRICE,DECIMAL NUMBERS);
if we have to diplay $480.00 as $480 simply use
if we have to display $480.00 as $480.0000 simply use
I hope this will help you….
