This is the same algorithm I implemented in lib/_float_formatting.py
ages and ages ago... It's not RPython as it uses long arithmetic, but
only boundedly so (I don't think it will use a number larger than
2**53) so you could probably fake it by using a pair of ints.
The problem with _float_formatting is that I never got around to
implementing the fixed formatting routines from the same paper (and
Gustavo hasn't either, AFAIK).
Cheers,
