title: SharePoint 2010: field formulas
body: <p>Does anyone know a way using either the SharePoint 2010 Client Object Model or the SharePoint 2010 web services to evaluate the formula for a given field?  For example, if I have a DateTime column whose default value is set to a formula like:</p>
  
  <pre><code>=DATEDIF([Column1], [Column2],"d")
  </code></pre>
  
  <p>or </p>
  
  <pre><code>=MONTH([TODAY])
  </code></pre>
  
  <p>I would like to be able to somehow evaluate this formula from a client application.</p>
  
  <p>Thanks in advance for any help anyone can offer.</p>
  
  <p><strong>EDIT:</strong></p>
  
  <p>I am dealing specifically with DateTime calculated default values which seem to be handled differently than a typical "calculated" field.</p>
