Is there a setting to add a suffix and prefix to a list(integer) field like there was in Drupal 6?
You can do it with Simple Field Formatter module, see the below screenshot



Which allows site administrators to easily control the display of
field values with following features


  
  Prepend the field value with specified text/HTML
  Append the field value with specified text/HTML
  Reverse the Field Value
  Trim the Field Value
  Convert the field value to lowercase letters
  Convert the field value to uppercase letters
  Convert the first character of the field value to uppercase
  Convert the first character of each word in the field value to uppercase (7.x-1.x-dev)
  Replace some characters with some other characters in the field value (7.x-1.x-dev)
  Link the field value to node(7.x-2.x-dev)
