For the most part, real logarithm functions are proved and complex logarithm functions are noted in the missing theorems list.
One big part is a proof of https://us.metamath.org/mpeuni/eflt.html via continuity (I don't know if there is an easier proof but this one works). Some consequences of eflt are included as well.
logfac seems provable but a bit involved, so it isn't included here.
