This add-in is very useful, and with the right formula discipline it works quite well.
However, when working with noise models and logarithms and exponents, it usually goes wrong, like when adding two dB values:
=10*LOG(10^(A1/10)+10^(A2/10))
you get:
Even adding extra brackets does not really make it right:
=10*LOG((10^(A1/10)+10^(A2/10)))
as:
The flying exponents can to some extend be controlled by adding extra redundant brackets, but is this really needed?
And the Log() is not really well positionend anyway. What it should look like is something like :
Thanks for those comments. We should be able to fix these bugs fairly quickly - there similar to another bug we've seen.
Our focus recently has been on a whole new excel equation, which we're release shortly also.
Incidentally.
This addin should always be mathematically consistent and correct. I don't expect users to have to add in extra brackets etc other than to simply change the output style. In all cases the rendered equation should be mathematically correct.
This biggest challenge we have is knowing when to remove brackets that are needed in Excel, but you may not want in the rendered equation - as your example above illustrates with
