I make this proposal right after your first message, before the discussion
came up. I don't object of my proposal being reverted to the "numerator"
version if this is favoured by others.

I suggest the discussion take place at https://oeis.org/draft/A033473

I agree, but  actually this is quite frequent when round(.) is used on OEIS.
I believe that rounding up 0.5 to the next larger integer is the default
(almost "universally" agreed upon), unless "rounded down" (= truncated) is
specified explicitely. (At least for positive numbers...)
