body: <p>I just started getting a weird <code>printf</code> output, has anyone ever seen this? Any idea what it could be caused by?

  <p><strong>Edit</strong></p>
  
  <p>Here's the code. I'm new to c so if anything (even if it's not causing the error) looks wrong or uncommon please tell me.</p>
  
  <pre><code>       printf(f2,"%8.31f\t%8.31f\n",x[0],x[2]);
         fprintf(f2,"%8.31f\t%8.31f\n",x[1],x[2]);
  </code></pre>
