For Put (Item : Big_Float; Exp => 0), we could spare time and space by
claiming less digits if we can know the decimal exponent E in advance.
We need roughly Aft + E digits. Any idea to do that quick?

Replace mpz_t with mpfr_t from libmpfr. Easy at this stage but
boring. That would make a wide range of new numerical functions
available (cos, sin, exp, ln,...). Please look at the end of
gmp-binding.ads if you're interested. Vincent Diemunsch work
at http://code.google.com/p/adabindinggmpmpfr/ may help a lot.
Port to other operating systems. This should not be very difficult as
long as the GNAT Ada compiler and the GMP library are ported on that
platform. It may be convenient to use pragma Import (Foo, "mpz_foo",
GMP_Prefix & "mpz_foor"); and something similar with MPFR_Prefix, but
it may be more complex than it seems, since there are MANY prefixes
used by the GCC version of GMP...
Add the complex type provided by libmpc, with conventions from the
ARM.
If somebody is aware about Remote_Types and such esoteric things,
please see what ameliorations can be made... Michael Roe seems to be
aware.
Child package Big_Rationals provides, guess what, an integer fraction
type. Get/Put/Image/Value are not provided for this type, since it is
hard to find something useful for everyone with bases, exponents,
space and fractions bar conventions...), and easy to build your own
procedures using the Big_Integer Text_IO procedures. If someone uses
it, (s)he'll have to define a clean interface.
