How can I change field suffix due to its value I have a field which is of type number. 

I have a view where this field is shown with its suffix. I want it to change when the value of a field is more than 1. 

Is it possible to do something? Maybe some preprocess function or some module? 

Thanks for any help.
Views Conditional would be worth giving a try. The module pages says -


  Views Conditional is a simple module that allows you to define
  conditionals (if xxx then yyy) with fields in views. Conditions
  include:
  
  Equal To Not Equal To Greater Than Less Than Empty Not Empty Views
  conditional allows you to output text based on the result of the
  condition.
