How to remove two decimal digits ?
In order to remove decimal digits in price of product magento, we need to custom some code :Go to this file : code/core/Mage/Directory/Model/Currency.php

Open code/core/Mage/Directory/Model/Currency.php Find the following code on line no 195 :-

Find this code:

public function format($price, $options=array(), $includeContainer = true, $addBrackets = false)
{
return $this->formatPrecision($price, 2, $options, $includeContainer, $addBrackets);
}

and replaced it by this code :

public function format($price, $options=array(), $includeContainer = true, $addBrackets = false)
{
return $this->formatPrecision($price, 0 , $options, $includeContainer, $addBrackets);
}

Clear your caches and it’s done. Cheers
