Mathematically, it's always 0, isn't it?
0.01% is a round issue only.
No Shin. Let me try to clarify my problem
I exported the data out the tableau work book. First i calculated the % of total for each month then i used the % of total for 201709 - % of total for 201609 = % of Total Delta
However, at the end i would like to see the result for each country as below
Count % of Total Delta BRAZIL 114 40.57% 0.01% <== 0.22 + (-1.04) + (-0.16) +1.37 + (-0.38) MEXICO 167 59.43% -0.01% Total 281 100.00% 0.00%
Please let me know if you have any idea how to do it.
Thank you very much
