title: Django - How to get the value of a decimal field of object
body: <p>I have looked through the QuerySet API reference and I couldn't find anything that allowed me to get the actual value, as a decimal, of a field of a specific object.</p>
  
  <p>Everything I've tried doesn't return it as the actual decimal value. For example, Hours.objects.filter(fullname=fullname).values(hours) doesn't return the number of hours as a decimal value. I'm trying to get the number of hours of a user, mathematically add a number to it (e.g. 15.5 + 4.25) and save it back (as 19.75).</p>
