I have it working correct on LO3.4.1. Started from scratch (new sheet) in

Steve,
It works properly here, too, with the proper cell format. Somehow the two
problem columns became typed as time rather than as number. When I figured
that out and changed the cell formats the display corrected.
The incorrect formatting might have been carried over from an existing
column when I added a couple of interior new columns.
Thanks,
Rich
Again, the number format has absolutely no influence on the formula
result. Never ever. Stop thinking in formatting attributes. They are
meaningless. It's all about numeric cell values.
=(A1-B1)*24 is the same as (A1-B1)/TIME(1;0;0). Both convert days to
hours. If the results happen to look different because you did not
format the cell explicitly, this is a merely cosmetic effect.
=TIME(1;0;0)=1/24 returns TRUE because both expressions are perfectly
equivalent.
=TIME(1;2;3) is just another way to calculate =1/24 + 2/1440 + 3/86400
which is 1/24 of a day + 2/1440 of a day + 3/86400 of a day.
In other words: 1 hour + 2 minutes + 3 seconds
You can format the result of =PI() in thousands of different dates,
times, currencies, percents with decimal commas and with decimal points
without ever changing the value of Pi.
