title: Sorting float values for averages
body: <p>I know generally why it would be advisable to sort a float at all in order to calculate the average of several values in array: you would risk adding together values that are farther apart gap-wise - and thus distort the overall value. </p>
  
  <p>But why would the accuracy further increase if you decided to order them not in ascending order, but descending order? I've come across a few average formulations for floats and have noticed a preference to sort them in descending order and wondered why this is so?</p>
