"Much of the problem with floating point is that we intuitively expect it to follow the math rules we're familiar with, but they seem to, but often don't." Well... maybe. I don't think most people have the foggiest idea what floating point numbers are, or what the Real numbers they approximate are, so the idea that people (a) have a solid understanding of Math (let's just say Real Analysis) and that (b) this solid understanding is violated by the behavior of floating point numbers is a bit of a stretch. E.g. I doubt many programmers realize that 1/10 doesn't have a finite binary expansion.
