title: How to avoid numeric exception : overflow in Maple 14?
body: <p>Maple 14 has isprime command which testing whether number is prime or not. It's allowed to write expressions as input data so we may write the next command :  </p>
  
  <blockquote>
    <p>isprime(2^(3^43-5)-1);</p>
  </blockquote>
  
  <p>but I get the following error when trying to run a test :</p>
  
  <p>Error, numeric exception: overflow</p>
  
  <p>So my question is how to avoid this overflow error ? Should I change default stack size  and if it's so how to do that on win 7 ultimate ?</p>
