What about 1/3*3? Because none of them will (Again, except for CAS mode).

Tim,
these calculations involve intermediate (rounded) 12-digit results.
From the user's perspective, LOG(81,3) is a single function, much like ^ or XROOT (I'm referring to the 48 as I do not have a Prime).
Yet XROOT(4,81) does return 3, exactly - even if, internally, it's also implemented using natural logs and exponentiation. The same ought to be possible with log?

Cheers, Werner
