Project Description:
Hi,

We have transactional e-mails in our magento store. In one transactional mail we ask for a 30% downpayment to transfer to our bank account.

Please see the attachment for how it is now and how it should be:

Current code:

Totaal bedrag: € {{var order.getGrandTotal()}}Aanbetaling (30%): € {{var order.getGrandTotal()}} (/30)

This code shows 4 numbers after the , like 319.0000 and it should be 319.00
This code is not able to calculate 30% from grand total > it's this part Aanbetaling (30%): € {{var order.getGrandTotal()}} (/30)

So we need ,00 and 30% of the grand total in the second part, can someone make it for us?
