Getting rid of encoding large numbers/binary-strings
in decimal was a very good thing. Conversion from
decimal to binary is simple but it is time and/or
space consuming. I looked it up in Knuth last time
when I saw the casual comment of it not being so.
From what I understood, the simple algorithms
all (both?) are O(n^2) time. If you want to do better
than that, they get complicated fast and you start
losing space (I think, mostly to store precomputed
multiplication results and such).
