2 things:

To be technical, your error (as you've explained it) is run-time, not compile-time error. A run-time error is something odd that happens during the execution of the code that you didn't expect. It may be a crash or just may not print what you thought it would.

The other "thing" is this: when do you need to print out floats? I dunno, maybe you do need them. Important values like motors are unsigned chars, however. Most of what you're working with is bits and chars. If you really need this to work, it's worth your time; otherwise, there are probably 400 better things to do.

Best of luck with it...
