I have a problem with calculating CPC in Tableau. I have the cost and the number of the click but Tableau is not calculating the right CPC. the formula I used : [Cost]/[Click] I attached two tables in this request. first shows the table in which I calculated all KPIs in Zeppelin. the second the calculation in Tableau.

The whole data set has many null and 0 values, but it is the same data set used in zeppelin

The result of CPC is not correct in Tableau.
