/* mpz_millerrabin(n,reps) -- An implementation of the probabilistic primality
   test found in Knuth's Seminumerical Algorithms book.  If the function
   mpz_millerrabin() returns 0 then n is not prime.  If it returns 1, then n is
   'probably' prime.  The probability of a false positive is (1/4)**reps, where
   reps is the number of internal passes of the probabilistic algorithm.  Knuth
   indicates that 25 passes are reasonable.

   THE FUNCTIONS IN THIS FILE ARE FOR INTERNAL USE ONLY.  THEY'RE ALMOST
   CERTAIN TO BE SUBJECT TO INCOMPATIBLE CHANGES OR DISAPPEAR COMPLETELY IN
   FUTURE GNU MP RELEASES.
