Invoice price calculation question

[koko20212021]

Hi everyone. I have a little issue.

On my invoices I had to add a second currency with static exchange rate - Default currency is EUR and I added also RON, with the following code.

<td class="total-row text-center">{($item.amount|replace:'€':''|replace:'EUR':'' *4.95)|string_format:"%.2f"} RON</td> 

The issue is that if total is ex: €49,99Eur  the equiv in RON will display ( on invoice pdf and view invoice )  with the earlier code : 242.55 RON  

But if we make a calculation: 49.99 x 4.95 = 247.45 

What is wrong ?
