Depreciation Formula Round to 0 decimal

Anyone know how to setup Depreciation formula with round to 0 decimal place?
I try many times and get syntax error.

I assume you should be able to use Floor or Math.Floor(Asset Cost/Estimated Life Periods). I’m not sure what coding that box takes.

I setup in EPICOR 9 before. It can work fine.
But now fail in EPICOR 10.
