Why?

Maybe someone has a better answer for you if you say what you want to do.
If your thinking of distributing a dll and having all the functionality of
Excel without actually having Excel, besides the fact you don't have the
license to distribute the dll and would violate you EULA, I doubt it is
possible anyway.

Hello,

Is there a way to determine the functions that get called when adding to
floating point numbers within Excel?

For example, let's say I put 2.43 in A1 and 5.43423 in B1. Then in C1, I
do
a SUM(A1:B1). I would like to know the APIs that get called to make that
SUM
happen and the DLLs that are the host of those APIs.

Thanks.
