Rounding up the amounts

Wow, what a fantastic product, just what I've been looking for.

With our financial year just begun and just a few invoices raised, I'm trying to mirror our existing system, but I can't seem to get Zoho to tally up correctly. It would appear it's not rounding up the amounts, but actually rounding them down instead.

Let me give you an example of what it should look like:

Item 1 �59 + 17.5% VAT (�10.33) = �69.33

This is what it currently looks like in Zoho Invoice:

Item 1 �59 + 17.5% VAT (�10.32) = �69.32

I believe it's not rounding up correctly as the VAT on �59 comes out at �10.325 and should rounded up to �10.33, but Zoho seems to be tallying it up at �10.32.

Is there any way I can configure this correctly or do you need to fix this in an update?
