title: Octave - how to operate with big numbers
body: <p>I work on RSA algorithm in octave, but it isn't working in proper way. Problem appears while i try to use "^" function. Check my example below:</p>
  
  <pre><code>&gt;&gt; mod((80^65), 133)
  </code></pre>
  
  <p>terminal gives me:</p>
  
  <pre><code>ans = 0
  </code></pre>
  
  <p>I cannot fix this stuff, it's funny becouse even my system calculator return correct number (54)</p>
