Data types in physics

Hi,

I submitted this question to sci.math.research but it was rejected for
being related to physics or computer science and not math perse.

I have been trying to classify data types in physics

http://www.densytics.com/wiki/index.php?title=Data_types_in_Physics

and I am confused about what is considered string (in the sense of
computer language terminology) and what is considered number or
quantity or magnitude in physics.

More specifically, looking at F in F=ma I see something like a pointer
to an address, not the address itself. Or if ma is number in a
spread*** cell, F is the name of that cell.

I know this is not how physicists see it. I am looking to find the
correct mathematical terminology so that I can state the problem
clearly. Do you know a field of physics or math that studies these
things?

Thank you for the help.
