No, the only operations that you do on money are
Add money to money
Subtract money from money
Multiply money by a scalar and convert the result to money

The only log functions that I see in the financial computations
are to compute the scalar factor which is multiplied by the principal.

It doesn't matter. The scalar factors would be computed in FP.
Any refinement thereto can only be done by trial and error.
