Re: John's asinh split versus convert-to-sortable...



All,

If I may temporarily take off my "acting chair" hat
(passing the chair back to Nathalie), and state
an opinion as a regular member, I must say I agree
with Arnold on this point.  However, I nonetheless
have found the discussion on splits interesting,
with possible good ideas for improvements to existing
algorithms.  In my opinion, "midpoint" is a bit different,
having a character of down-conversion from interval
to floating point.

That said, if there is sufficient support for including
splits in the standard, I will certainly process such
motions in an unbiased way.

Best regards,

Baker

I mention this as I think that none of these splits should belong to a standard, because how to split is a matter of algorithm design and not one of standard behavior. Any particular choice will be artificial - a very bad sign for something
that should become standard.
