Round-Half-Even (Banker's Rounding)

Round-Half-Even (Banker's Rounding)

I'm trying to come up with the algorithm to round a number with the half-even method since the default round formula in Zoho Creator uses the standard Round-Half-Up . See here:  https://www.eetimes.com/document.asp?doc_id=1274515#A2

The problem is my app is integrated with my accounting software, which uses the banker's rounding method, and as a result I'm getting conflicted values.

Anyone has experience with using different rounding methods in Zoho?
