Try use event observer.

config.xml

<events>
    <payment_method_is_active>
        <observers>
            <namespace_module>
                <type>singleton</type>
                <class>NamaSpace_Module_Model_Observer</class>
                <method>paymentmethod</method>
            </namespace_module>
        </observers>
    </payment_method_is_active>
</events>

observer.php

<?php 
class NamaSpace_Module_Model_Observer{
    public function paymentmethod(Varien_Event_Observer $observer) 
    {
        $method = $observer->getEvent()->getMethodInstance();
        $quote = $observer->getEvent()->getQuote();
        if($method->getCode()=='COD')
        {
            //get grand total and modified it.
        }

    } 
}

Use the PHP function round() to round off the price.

Example is below:

echo round(3.5); output: 4
  • Welcome to Magento SE. Changing the output and then still charge the original price is certainly not what OP wanted, so unfortunately this answer is not very helpful – Fabian Schmengler Jan 13 '17 at 12:45
