I copy these file from core to local folder from app/code/core/Mage/SalesRule/Model/Quote/Discount.php.

**WHAT I NEED TO DO IS ROUND OFF DISCOUNT VALUE WHICH ALSO ROUND OFF TOTAL VALUE AS WELL **

enter image description here

I used round function :

 public function fetch(Mage_Sales_Model_Quote_Address $address)
    {
        $amount = round($address->getDiscountAmount()); /* round up value */

        if ($amount != 0) {
            $description = $address->getDiscountDescription();
            if (strlen($description)) {
                $title = Mage::helper('sales')->__('Discount (%s)', $description);
            } else {
                $title = Mage::helper('sales')->__('Discount');
            }
            $address->addTotal(array(
                'code'  => $this->getCode(),
                'title' => $title,
                'value' => $amount
            ));
        }
        return $this;
    }

Magento pass discount value as negative value in calculating function,

E.g

Subtotal = Rs. 100

Shipping = Rs. 20

Discount = Rs. 20

Then,
Grand Total = Rs. 100

Here,

Magento calculate the discount amount (-20) so, Function just add all the values with (+) sign.

Like , 100 + 20 + (-20) = 100

            }
            $address->addTotal(array(
                'code'  => $this->getCode(),
                'title' => $title,
