Provided sprintf("%f", 2000000000000) doesn't work either, you'll have to
code a solution.

I have a whole set of routines that do things like this, called basebag.e,
but I haven't got them on this server yet (aargh!).

They're of the form (off the top of my head):
function seq2atom(sequence seq, numbase base)
  -- convert the "seq" string of a number in base "base", into a real
  -- floating point atom.
end function

function atom2seq(atom number, numbase base)
  -- convert "number" into a string representation of itself in base
  -- "base" with floating point handling.
end function

function baseconv(sequence seq, numbase from, numbase to_)
  return atom2seq(seq2atom(seq, from), to_)
end function

So, baseconv("3.14159265359", 10, 16) returns something like "3.243F6A88"
and baseconv("3.14159265359", 10, 2) returns:
        "11.00100100001111110110101010001000001" (!!!)

I'll put basebag.e on my site sometime around the end of this week...
