--- Comment #12 from B Eggen <bre08 at eggen dot co.uk> ---
Thanks for your explanations, and for reminding me of the excellent library=
 etc
by David Bailey.  My original quest was to have a fast method to decide for
large integers quickly whether they are perfect squares. I prob need to do
something different to avoid the rounding pitfalls (:-)

PS (and maybe I need to post this separately as a suggestion) - will there =
be a
fast "octuple-precision floating point / integer" library (i.e. 256 bit) fo=
r C,
C++ and Fortran, or is using something like GMP the only way forward ?

BW, Bernd=
