Hii all

Hi Vallirajap 

1.45E-13 (scientific notation) is equivalent to 0.000000000000145 in decimal form. It is every close to zero. This happens as when doing the calculation, it may actually be calculated with the decimal numbers, so the result will have some small decimal places. To deal with it, we can give the result a specific number of digits after the decimal point. For example, if you want the result to be a whole number, you can use ROUND function 

New = ROUND([measure1] + [measure2], 0)

ROUND function (DAX) - DAX | Microsoft Learn
