I have a fun memory of the yellow Mindstorms set. Apparently, the visual programming environment was just a thin wrapper on top of C, and people quickly came out with simple IDEs that let you program the brick in C. I tried to program a musical sequence, and was mystified when programs involving simple decimals didn't work. I didn't understand at the time, but the Yellow Brick didn't have any floating-point support! I eventually just faked it with a good-enough approximation of using integers to emulate fixed-point arithmetic.
