I think I'm with @qinqingege on this one. This is not about removing the `[]` functionality as @PaulStoffregen says but about making it more array-like. Why can you do ```arduino...

As a workaround, use `(floor)(x)` and `(ceil)(x)`, which will not use the macro but the actual function. Alternatively, you can create a new tab in your Arduino project with a...

...well, I did say it was a workaround, didn't I? :) In any case I think Arduino.h will eventually have to be purged from macros and instead use standard C++...
