title: Rounding float/decimal to 3 decimal places exactly?
body: <p>I know there are many questions asking for this, but I have tried quite a few of the solutions but none seem to work exactly how I need it!</p>
  
  <p>Most solutions work, however in my test data I have the <code>float</code>: <code>0.08095238095238096</code></p>
  
  <p>If I round this to 4 I seem to get; <code>0.081</code> when I need to have <code>0.0809</code> and not rounded up that last place.</p>
  
  <p>Also am I best using float or double for this type of number?</p>
  
  <p>Thanks</p>
