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.
