title: Where clause and truncating decimal points
body: <p>Values in my table have a number of decimal points:</p>
  
  <pre><code>20.828292
  21.9292992
  ...
  </code></pre>
  
  <p>I need to query the table to find results that match but to only 1 decimal place.</p>
  
  <p>So where 20.8 would match the 20.828292.</p>
  
  <p>Can I do this with SQL? How?</p>
