title: Django, how to fix max decimal in floatfield in annotate?
body: <p>I have the following code: </p>
  
  <pre><code>annotate(totale=ExpressionWrapper(Sum(F('prezzo')*0.50/12),output_field=FloatField()
  </code></pre>
  
  <p>but in my template I have as results (for example) 145,555555555555555555555555 instead 145,55</p>
  
  <p>I have added <code>|intcomma</code> but the result is the same.</p>
  
  <p>How could I fix this ??</p>
