Question for humans: I'm planning on merging this into sage so that
other developers can help grow it and it's not just me working on it. Would
it be better to first wait for any bugs that people might notice and then
add it into sage? Or should I just go ahead and start merging it in and any

The next step of integration could be to add this package as an optional
package to Sage, see https://github.com/sagemath/sage/issues/31164

The following is the proper way to extract digits
sage: tanh(91).numerical_approx(digits=10)
1.0
sage: tanh(91).numerical_approx(digits=100)

I was able to install SageMath and get it running. Thank you very much for
all of your help.

The main relevance of classifying errors properly in python is for
try/except. Generally, a try/except should be tight both in code guarded
and in errors caught. An `except RuntimeError` is almost certainly a bad
idea. `except ZeroDivisionError` looks quite reasonable. `except
ValueError` or

gp computes it both ways :)

The ValueError is correct -- the quantity is so close to 1 that numerics
cannot tell whether the floor is 0 or 1. You could report a bug to gp,
though, because the correct answer is 0, not 1.

The NoneType error is presumably a bug in the sage wrapper code.
Possibly related is that Maxima cannot compute the sum with its
default algorithm. It does have a simplify_sum function that can do it
though:
(%i19) load (simplify_sum);
(%o19)

You're misunderstanding what a catch-all means. It means *any* type (of
error) is reasonable. To put it mathematically, catch-all means union (of
sets), but the Python doc means difference (of sets).
An assertion is slightly different. It can (in principle) be turned off and
is just used for
