title: What is the performance impact of saving and fetching fractional double field data in postgres database
body: <p>What is the performance impact of using “fraction data fields” vs. “regular number field” in Postgres?</p>
  
  <p>For instance:
  The numbers 1,2,3,4,5,6,7,8
  Vs.
  The numbers: 0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8</p>
  
  <p>I would like mainly to sort according to this field and sometimes to filter.</p>
  
  <p>Thanks,
  Shay</p>
