Voltage at IC pin

Using Arduino General Electronics
1

Just making sure my thinking is correct. If I have 12 volts + going though a 5.8 volt zener and then into a pin of an IC which is for voltage sensing, that pin would "See" 6.2 volts? Is that right? I realize this is a basic question but I'm tired and I just want to make sure my thinking is right on this.

Thank You

Can you post a schematic of the situation? A schematic is worth 100 words and is far easier to understand without ambiguity.
