Logarithms

How the hell do you mathematically calculate algorithms? In the past, we've always used logarithm charts for reference and today we just use the calculator. But how does a calculator do it? I asked a math teacher and he had no clue and I asked the #math channel on Freenode where someone stated that I'm an idiot and "processors now adays just store logarithm charts directly in the processor". So how does one go about calculating a logarithm?
Use the taylor series, or alternatively repeatedly call pow() and home in on it (this is slower than the taylor series).

I've had similar responses to, frankly enough, similar questions. These are usually the people that don't have a clue and give their non-technical / non-practical view of a non-existent solution; in this context, how would the charts be directly in a processor?
Sadly, I don't know the answer myself, but rocketboy seems to know more about it.
