First create currency class in path /app/code/local/Mage/Directory/Model/Currency.php

copy the content from file in core /app/code/core/Mage/Directory/Model/Currency.php and paste in your new file /app/code/local/Mage/Directory/Model/Currency.php

Go to line no. 222 and find code your file

return $this->formatPrecision($price, 2, $options, $includeContainer, $addBrackets);

and replaced it by this line :

Clear your caches and it’s done. :)
