I think it’s better if I just open a new thread about this again now. It can be merged with the other one once the purpose is done with.
Anyway. My updated calculator source code is on the GitHub repository now.
I’m having trouble getting any tests aside from the 1 through 8 and 10 in “Tests” to pass. I’ve tried everything I can think of for tests 8, 11 and 14.
So yeah: What am I doing wrong or missing here? Any help is appreciated. Thanks.
