It is probably related to what functions like [HV]LOOKUP do when used on
a sorted range, e.g. the last element <= query is picked if sorted

/me notes that we did not document that but mention that in case there
would be more than one consecutive match, the result returned would be
arbitarily picked out of those, but that isn't true. The last match is
returned. At least that's what I found out when implementing these
functions, and it somewhat makes sense. I'll add details to the spec for
[HV]LOOKUP as well.

Of course ECMA/MOOXML didn't document it either.


Automatic string conversions considered dangerous. They are the GOTO statements
of spreadsheets.  --Robert Weir on the OpenDocument formula subcommittee's list.
