mpf_t precision problem?

  exact same problems, perhaps worse.
  
You ask for 220 bits of precision, corresponding to about 66 decimal
digits.  GMP rounds the requested precision to a full word (aka limb),
meaning that you get 256 bits of precision, about 77 decimal digits.

The print statement for reciprocal is incorrect.

No GMP bug.
