If you end up coming up with a nice library design, you may want to generalize these operations from Double-valued logarithms to conversions between a Lie group and its corresponding Lie algebra.
Abstracting from the positive reals to (possibly non-abelian, complex?) Lie groups is a rather steep generalisation. Is there no useful intermediate step? Or is it the case here that the most general form is also the simplest (does away with inessential details that distract from the core concepts)? I do recall that for me at one point Calculus in Banach spaces was easier to understand than Calculus in R^3. The generalisation was cleaner. -- Viktor.
