If it's just arguing about which spelling to use, there should be
nothing wrong with "." rather than "-r", and it has the huge
advantages of simplicity and consistency.

Actually, using Ben's (slightly) extended definition, you could even
use ".r" if you're wedded to the idea of having something other than a
plain number.
