Interesting, I didn't know that! I didn't know him until the 90s, and didn't meet him in person until his CodeCon presentation.

What I was trying to express—perhaps poorly—is that maybe floating-point support would have been more effort than the entire Integer BASIC. (Incidentally, as I understand it, nobody has found a bug in Apple Integer BASIC yet, which makes it a nontrivial achievement from my point of view.)
