title: How do I retrieve decimals when rounding an average in SQL
body: <p>Here is my SQL statement</p>
  
  <pre><code>SELECT ROUND(AVG(column_name), 100) 
  FROM [database].[dbo].[table]
  </code></pre>
  
  <p>The answer I retrieve is <code>3</code> with a possible range of numbers between <code>1 - 5</code> in 908 rows.</p>
  
  <p>I need it to say <code>3.0</code> or <code>3.09</code>. Is this possible?</p>
