comment How to use variables in calculations when defining a new TikZ command
Replace your defs with \pgfmathsetmacro\xd{...} etc. It's an expansion problem.

comment How do I remove the number in the end of a reference?
I'm voting to close this question as off-topic because it was a class/package clash cleared by removing a certain option given in the comments.

comment In tikz is there a way to set a node style to center the center of each node within a given scope
@Kpym It is about the paths not the syntax. Read my first sentence. I'm not making any claims about the syntax. That snippet I wrote down is the resulting path that accumulates. You are also not answering why {(A) --} is an invalid syntax. Why would brace pair matter if it is merely a group? That's what I'm trying to draw your attention to. It's not just a mere TeX group.

comment Squeezing scientific paper to fit within page limits
You don't get to typeset the journal version. If accepted you will have all these tricks removed and you will pay extra page charges so this will be useless and in fact annoying for the reviewers.

comment In tikz is there a way to set a node style to center the center of each node within a given scope
@Kpym A TikZ scope is not exactly a TeX group. In your example your first one is a complete path because you have the implicit first point. Your second one is not complete. So you might choose to say this is because of the scoping behavior. I consider this as a frontend property that is not necessarily valid for PGF level syntax where grouping is not the problem at all. If it was like as you described, why would scoping matter for path to be complete or not?

@Kpym Path declarations are global. You can have such things for example to change rounded corners temporarily etc.

@azetina Yes but the name of the tangent is available later so you can draw from that node to wherever you want.

comment Parsing CSV with comma as decimal separator in pgfplots
use comma won't work. Separate your data to integer and decimal part and concatenate in a separate column as text in Excel with a period char.
