回答1:

[magento]\app\code\core\Mage\Checkout\Helper\Data.php

add below function

public function customformatPrice($price)
{
        return $this->getQuote()->getStore()->customformatPrice($price);
}

add below function in [magento]\app\code\core\Mage\Core\Model\Store.php

public function customformatPrice($price, $includeContainer = true)
   {
          if ($this->getCurrentCurrency()) {
          //sets the floating point precision to 3 points

          return $this->getCurrentCurrency()->format($price, array('precision'=>3),     $includeContainer);

         }  
         return $price;
   }

you can use above like

//magento default call
echo Mage::helper('checkout')->formatPrice(3000.1231);//Rs3,000.12
echo "<br>";
//customized function call
echo Mage::helper('checkout')->customformatPrice(3000.12313);//Rs3,000.123

actually you can direct modify the formatPrice() in [magento]\app\code\core\Mage\Core\Model\Store.php but as you want both format we create custom function

hope this helpful for you

open [magento]\app\code\core\Mage\Core\Model\Store.php

public function formatPrice($price, $includeContainer = true)
   {
          if ($this->getCurrentCurrency()) {
          //sets the floating point precision to 3 points

          return $this->getCurrentCurrency()->format($price, array('precision'=>3),     $includeContainer);

         }  
         return $price;
   }

Note:- change array('precision'=>3) instead of array()
