title: linq.sum is rounding
body: <p>I have the following line in my vb.net website:</p>
  
  <pre><code>totCost = outstandingTimesheet.ClaimLines.Sum(Function(x) x.TotalLineCost And x.Queried = False)
  </code></pre>
  
  <p>The sum is bring rounded though and I can't work out why...</p>
  
  <p>Any ideas?</p>
  
  <p>I don't believe it is just a case of formatting the output it is more what is going on within the sum.</p>
  
  <p>Is that correct?</p>
