This. Sure, floating point numbers come with a footgun, but the title is so clickbaity, would it really hurt to name it: "What I wish I knew about floating numbers before relying on them?"

I think it's common to just not be taught floating points need to be handled a lot differently than whole numbers, so the common experience is getting bit by it. I don't remember ever being taught that in my traditional schooling, personally.

I remember covering how floating point were stored, but I don’t remember going all that deep into how that affected arithmetic.
