title: GMP variable's bit size
body: <p>How to know the size of a declared variable in GMP??or how can we decide the size of an integer in GMP?</p>
  
  <pre><code>mpz_random(temp,1);
  </code></pre>
  
  <p>in manual it  is given that this function allocates 1limb(=32bits for my comp) size to the "temp"....
  but it is having 9 digit number only..
  SO i dont think that 32 bit size number holds only 9 digits number..</p>
  
  <p>So please help me to know the size of integer variable in GMP ..</p>
  
  <p>thanks in adv.. </p>
