Fine - I agree - I'm only reporting what I have seen used elsewhere.
>>> T edit_distance(T a, T b)
>>> Returns the number of floating point representations between values a and b.

The edit bit sounds odd to me - and uses I have found are applied to *strings* when the name makes some sense - the number of typing
mistakes you need to make ;-)
Can you enlighten me on why it is a "technically accurate" name here?
PS Are we choosing names for posssible specializations of other types than floating-point? derived FP, integer, char, strings,
