title: How to Get enum item name from its value
body: <p>I declared a enum type as this,</p>
  
  <pre><code>enum WeekEnum
  {
  Mon = 0;
  Tue = 1;
  Wed = 2;
  Thu = 3;
  Fri = 4;
  Sat = 5;
  Sun = 6;
  };
  </code></pre>
  
  <p>How can I get the item name "Mon, Tue, etc" when I already have the item value "0, 1, etc."</p>
  
  <p>I already have a function as this</p>
  
  <p><code>Log(Today is "2", enjoy! );</code></p>
  
  <p>And now I want the output below </p>
  
  <blockquote>
    <p>Today is Wed, enjoy</p>
  </blockquote>
