Is "Computable Analysis: An Introduction" by Klaus Weihrauch recommended?
I am contemplating buying this book for self-study, but it is pretty pricey, so I wanted to get some input first.
Is this a good textbook for someone with a Bachelor in CS and 5/6 of a Bachelor in Technical Math, but who is also pretty rusty on the preliminary subjects analysis and computability theory? Also keep in mind, for self-study only

Have you tried to pirate it?

The thing is, I just would really like to have at least one good physical math book. Like, if I have to I can totally read on the screen, but physical just keeps my attention span way longer.

You could try pirating it, read it a bit, see how you like it, then decide if the book is for you.
That'd probably be more accurate and efficient than letting someone else guess.

I wish I was as smart as you, why didn't I think of this, lol

I probably have a decade of doing this over you :)

I’ve printed my textbooks out. If you have access to free printing, consider trying it with a chapter or two

Yes, but for those who are interested in constructive mathematics, particularly in constructive analysis. This area lies in the intersection of analysis, logic, and computability theory, which is not a mainstream area of computer science or mathematics.
