The straightforward algorithm -- repeated division by the new base --
is O(n^2). (Here n is not the number being converted, but its size,
which is to say its log.)
I don't know of any better algorithm. Nor, really, of any other
algorithm.

I suppose this question is better addressed to math-fun, however, I do
not think my work self belongs to math-fun.
At any rate, does anyone know anything about the efficiency of base
conversion between non-homomorphic bases, e.g., 2 and 10?
