title: SQL set floating point precision
body: <p>For a SQL int that is being converted to a float, how do I set the precision of the floating point number?</p>
  
  <p>This is the selection I would like to truncate to two or 3 decimal places:</p>
  
  <pre><code>AVG(Cast(e.employee_level as Float))avg_level,
  </code></pre>
  
  <p>Thanks!</p>
