Actually, I meant (2^n)-1. I tested (2^n)-1 for n = 16 and 24 with single precision floating point numbers pretty extensively and carefully and they are transparent as well. There is presumably some reason for this beyond coincidence (not enough of a change to snap it to the next quanta?), but I don't think I want to think about it anymore.
