title: Should I use Sharepoint Number column types to store monetary values?
body: <p>In SharePoint I can create a list column of type 'Number'. I need to store monetary amounts and would like to be able to use this column type rather than having to create a new one.</p>
  
  <p>Are values of this type stored and manipulated by SharePoint (e.g. when summing values in a list view) to prevent loss of precision (i.e. not as some kind of approximate floating point type)?</p>
  
  <p>I have looked at currency columns but they seem to force display of a currency unit which doesn't make sense in my application (and I have a suspicion that they are stored as 'Numbers' under the bonnet).</p>
