Let's ask another question: If Arduino sells a cpu with double-precision fpu in the future: will they use single-precision-consts?
Somehow I doubt they even consider these sorts of performance questions....
I'd be really surprised if they did anything other than just going with the compiler default. In fact, I'd be surprised to hear they ran any float vs double benchmarks. This just isn't the sort of thing they've ever seemed to have any concern.
