Floating Decimal Package/Library?

["Warren W. Gay VE3WWG" <ve3wwg@cogeco.ca>]

Since the PostgreSQL group have expressed no
interest in supporting floating decimal
routines for the client, I wonder if anyone
in these groups know of an Ada package (preferred),
or C/C++ library that supports arbitrary
prcecision floating decimal values. I could
hack the PostgreSQL back end C routines, but
this may not be practical.

The GNU GMP library comes close, but its
floating support library uses binary
arithmetic (this is a no-no for financial
work). I've suggested that they augment GMP
with this support, but I'm not sure what
response I'll get to the request.

I am looking for a PD/GPL/Open Sourced work.

Thanks, Warren.
