I talked to support today about this issue and they too could not explain it. Fills forms being rounded and added together is a crucial part of my job and I'm finding that oftentimes the rounding is incorrect by .01, often because is was incorrectly added after the rounding process.

I know Adobe has the ability to round numbers in the fill forms to a specific number of Decimal places, but what I am sort of seeing is that it doesn't matter what rounding you use, Adobe adds the raw numbers (Which defeats the purpose of rounding).

I have attached a file that contains an example of the incorrect addition based on the rounded values. the 2 top fill forms in the red box add together in the last fill form in the red box. If you checked the addition manually you will see that the addition is off by .01. But, if you add together the raw values (Unrounded) that is technically the correct value rounded.

No one can explain to me why this is off by .01 when it very clearly should be adding the rounded values instead of the ungrounded raw values.
