  Dear Cory,
  If you want to display the result as 0 when zero exists in one cell, please apply this formula: =IF(A2<>0,(A3-A2)/A2,"0"). You can change the second 0 to any data as you need to display as result.

A fair answer to the problem but what about negative numbers or cases where one on the numbers is zero - what would the formula look like in these cases?
