Yes.
 Input: 2 registers

  Temp: 1 register

Output: 1 register
-------------------
 total: 4 registers

Required at compile time: 1 subroutine to do something nice with the Output
value and it can then munch it. For example, you can shift the output
register out a port pin, leaving behind a zero.

The only thing that the main routine has to do is call the subroutine for
each digit of output with a valid number between 0 and 9 (or '0' and '9') in
the output register.

Possible improvements for extra credit (not in my code):
It would be nice if it had an option to output a "." after some number of
digits passed as a third input.
It would be nice to optionally skip leading digits that are zero.

Code that cannot be written for the PIC:
A general purpose routine that is given a pointer (FSR) to a register
holding the radix and followed by a count of the number of following bytes
that contain the binary number to be converted. Output each digit as it is
developed.

Do we get to destroy the original 16 bit number?
