A short cut that will get you close BUT NOT DEAD ON ACCURATE, when you don't have a calculator handy, Take the higher number of the 2 direction X or Y doesn't matter. This is stuff you can do in your head.
Example: Let's say X is .0032 is out from 0, and Y is .0012 So take your X times it by 2 =.0064, because it's the higher number of the 2, take your Y cut in half .0006 add it together .0064+.0006=.007 <<<<Position Now using the correct formula as stated above your position is actually .006835
Since I did have a Dyslexic moment as
MetsoMetrology pointed out. lets say X is .0023 and Y .0012
X doubled =.0046 + half of Y is .0006 = "(.0046 + .0006 = .0052)"
With the true formula comes out .005188

Just something I was fiddling around with to try to help machinist who may not have known the formula. In case I'm not around to help them, to raise a red flag on themselves like the sample above .007 maybe they have .010 tolerance "Hey Somethings wrong" because most of the time they have that thinking of +/- .005 for tolerance. I tell them it don't work that way.

KIRBSTER269 I've run into the same issue trying to explain true position to machinists who just want a simple answer like a plus/minus. I ended up printing out a true position chart to give them a general idea and now I can show them another way. Thanks!
