title: Should I use decimal, float or double for this simple math result?
body: <p>I'm doing some really simple math and saving the result to a MS SQL2008 DB.</p>
  
  <p>I'm <em>averaging</em> out the some numbers, which are byte values between 1&lt;->5. I wish to record probably 2 decimal places only. I don't care about rounding for the 2nd decimal place (eg. a 1.155 == 1.5 or 1.6 .. i'm not too phased).</p>
  
  <p>So .. should i store the average result as a float, decimal or double?</p>
  
  <p>When i check what LINQ returns, it can return all three values!</p>
  
  <p>Lastly, what would be the relevant SQL datatype field, also.</p>
  
  <p>cheers!</p>
