Hey,

if it automaticly rounds the outcome of (value 1 + value 2) for me, i get wrong outcomes.

Excuse me if i’m being stupid, but your number is going off to infinity…

So there has to be rounding?

I’m probably misunderstanding… But I tried to suggest (badly) in the previous thread, that it’s surprisingly hard to establish from the calculating values whether a calculated number will be correct to a specific decimal place.

My experience with your method is that it works for 99% of cases. I showed a graph which instead works off the calculated values, finds the surrounding correct numbers and compares them.

Apologies if I’ve gone off on a tangent.
