title: Why does >= return false when == returns true for null values?
body: <p>I have two variables of type int? (or Nullable&lt;int&gt; if you will). I wanted to do a greater-than-or-equal (>=) comparison on the two variables but as it turns out, this returns false if both variables are null, while obviously the == operator returns true.</p>
  
  <p>Can someone explain to me why that is logical because the semantical definition of the >= operator contains the word "or"?</p>
