RE: CAS Simplify(log10) always changes to LN
Nearly all more advanced CAS systems do not have implemented a base 10 and use a natural log for everything. In fact, they all just call it "log". The Prime CAS follows that convention and we had to do work to get "log" renamed to "ln" for the cas and "log10" lowercase as a base 10.

"log10" is implemented as a purely numeric command on the CAS side as the concept doesn't have the concept of log in anything BUT e (which is the standard as I mentioned). It doesn't have a symbolic equivalent.

Personally, I'd love it were it to be handled better but that depends on someone encouraging the CAS author to do it! Smile
