Understanding Floating Point

I wrote an interactive introduction to IEEE-754 floating point and would love some feedback.

My main issue with existing treatments of this topic (and internet tutorials, broadly) is that they ask too little of the reader. I wanted to structure this around a sequence of questions for you to answer, using interactive widgets and optionally an LLM tutor/grader. Basically: you progress in the tutorial by demonstrating your understanding.

The feedback I'm looking for is mostly around structure. Does it help to have the LLM available? Did you engage more with this than you would have with a standard tutorial? etc.

btw using the LLM is optional, and requires a valid email address (just to limit abuse). If you decide to do it on your own, you'll still be asked the same questions, you just won't be able to go back and forth with the LLM or have your answers graded.
