Looking for a SUM math function for calculation box

Hello. I'm creating forms using both currency converter and form calculation widgets. I'd like to add the converted currency amount, including cents, to another amount using the calculation widget, but the only math functions I have found round the sum (floor, ceiling, round). Is there a function for simple addition that doesn't round?

I checked your last form and did not find any calculation widgets. Which form are you referring to?

Please provide the link or the name of the form, so we can check your setup and suggest a solution.

We will wait for your response.
