   Hello to all,

   Can anyone tell me if I can assume exact division for mpf_class?

   For example can I assume that
   mpf_class( 6) / mpf_class( 3)
   will return mpf_class( 2) ?

   Thanks in advance

I don't know for mpf, but mpfr guarantees correct rounding, which implies
that if a division is exact, you get the exact quotient. See mpfr.org for
further details.
