Exactly 64 bits

[Paul Zimmermann]

       Dear Mahmoud,

currently it is not possible to compute with floating-point numbers of exactly
p bits with GMP's mpf. I suggest you try MPFR (www.mpfr.org). See in particular
http://www.mpfr.org/faq.html#mpfr_vs_mpf .

If you have already written programs using mpf, you can simply convert them to
using mpfr using the instructions on http://www.mpfr.org/faq.html#mpf2mpfr .

Best regards,
Paul Zimmermann
