We do have next() and prior() (not abbreviations!) already, which have meaning for iterators, integers, etc.
Doh! So why didn't I remember that! next and prior sound entirely intuitive to me. However John has specifically limited his question to floating-point types. (I'm not totally convinced this is wise). I think many novice non-mathematician, but not entirely floating-point naïve, users will want these functions. But none of suggestions so far for the difference or distance really grabs me. Complicated mathy terms like edit_difference and distance will not be what the above users will be looking for, even if they are what they need.
