why does this calculator get 999+ bit integer limits wrong? Also, why is infinity 2^1024 or higher while unendlich is 2^4096 or 2^8192 (I couldn't remember which one it was)?
Despite looking like a scientific calculator, it’s not. It’s a computational engine. However, a few years ago it joined the European calculator union, and now it mostly acts like a calculator. With the proper mix of sweet-talk, curses, and button presses, this computational engine will still give high-precision results for some large integer and small decimal equations.
There is a prerequisite for success: you have to be smarter than the computational engine.
This stops most users in their tracks.
