  I would like to write a mpz number in a .txt file (or a .doc file). What is
  the fastest function to do this? Could you post a little example source code
  (for beginners like me)?
  
There is a very useful document included with GMP that answers
this and many other GMP-related questions: The GMP manual.

(It is available online too: http://swox.com/gmp/manual/)
