INR货币的Prestashop Bug

I just came to know about one bug in Prestashop, that when I select the default website currency as INR (Indian Rupee), then the Prices are shown with comma in place of dot (.).

Here is the screenshot http://i.imgur.com/wb8FG.jpg
I have shown the bug with a red arrow and circle.

And one more thing, the older price which is crossed is lower than the current price. but it says Reduced Price.

How can I remove this bug?

It's not bug. But it can be changed from admin part.

You can configure this from the back-office, in tab Payment>>Currency, Select the currency you want to change an you will have the field "Format"

Edit: In new version (Ie: 1.6.0.9 which i have tested) It's in Localization > Currencies

It's not bug. You can configure this from admin Localization > Currencies
