I don't know.  

I've not  really been following your adventures in bignum very carefully.
They end up with what is to me walls of unreadable code, without any
useful explanation or challenging questions.

Because I have done something similar before in another language, I'm at
least somewhat curious, and would actually *like* to find your work
interesting.

If I understand correctly, you want a function to convert a number 
specified in one base into another.  That's fine.  But these are not
standard Javascript numbers, but your implementations of bignums.
How are these represented?  Are they arrays of integers representing
"digits" of your numbers?  If so, is the most significant or least significant digit first?  Do these represent just integers, fractions, 
fixed "decimals", or some other format?

Without understanding this, I'm not likely to dig into code I find
poorly formatted in order to find problems, nor to offer my own 
alternatives.

But I am curious, and might if I did understand your requirements
better, be willing to spend some time trying my own hand at the
issue.  (The emphasis is on _might_!)
