Re: [libreoffice-users] Error in Calc logical functions

I had another play with this LO logic buster this morning.

Whilst in Lotus 123 would only need  @IF(A1>10,"True","False")

the way LO works the formula needs to be:-( placed in say B1 looking at 
cell A1) to cater for LO's rationale and possibly to cover prior versions.

=IF(A1="","",IF(A1>N,"",IF(A1>10,"True","False")))

N has to max out above any number in your list (eg 10000000) as  it 
would appear that any Letter is seen by LO as greater than the highest 
possible number, to block this and to prevent the table seeing Letters 
as Numbers you need N.  With N in place, if you type in a letter  into 
cell  A1, then B1 remains blank and does not to give a false positive 
(or negative).
