Computer science might also describe '=' as A is copied from B.

How about:
'=' describes an proximity relationship between two measurements, where the
distance between A and B approaches zero to within some arbitrary threshhold?
Just by changing the threshhold, we can say that two things are equal. For
instance, my mom and dad live in different cities, but if I move the distance
threshhold up: They still live in different states, but they live in the same
country/continent/planet/galaxy. I would continue with same universe, but I
don't have the distance between two universes to work with in this implied
measurement of length.

I can therefore say that '=' is a partial description of a distance delta less
than a threshhold, which assumes the reader will know the scale of the
threshhold, usually based on S.O.P. for units of measure employed. Seems like it
might even be more appropriate to call it "less than e away from", but that's
just hard to pronounce.

Maybe a better symbol would include the distance threshold under which we choose
to ignore differences:
 A =e= B

If we were free to designate the unit of measure for a given application, I
would propose using length e as unit length, resulting in integer math.
