title: what is the point of using ternary operators instead of IF THEN?
body: <p>why make things more complex? why do this:</p>
  
  <pre><code>txtNumerator.Text = 
       txtNumerator.Text == "" ? "0" : txtNumerator.Text;
  </code></pre>
  
  <p>instead of this:</p>
  
  <pre><code>if txtNumerator.Text="" {txtNumerator.Text="0";}
  </code></pre>
