title: maxima fails for very simple equality (is equal)
body: <p>I have a very simple numeric comparison for which maxima is failing. I turned on verbose mode and debugmode but not able to see any additional detail. Is there something I need to specify (I tried different values for fpprec, but no use). </p>
  
  <pre><code>(%i2) is(equal(18225979/30454181, 0.5984721441039565));
  
  (%o2)                                false
  </code></pre>
  
  <p>As long as arguments are equal up to 12 digits after decimal, I want maxima to return true. Thanks in advance for your solutions and suggestions.
