Hii all

[Vallirajap]

I face one type of scenario newly. 
I have two measures. 
1. [measure1], It returns a value in minus (-254). This measure 1 has the addition of two more measures. 
           For example: Measure1 = [measure5] + [measure6] + [measure7]
2. [measure2], It returns the same value, which is 254. This measure also has a calculation of two more measures.

Now, I try to sum these two measures to get a value of 0. but the measure returns (1.45E-13).
New = [measure1] + [measure2]       //The value return is (1.45E-13).

When I try to subtract these two, it displays the correct answer.
New = [measure1] - [measure2]       // The value return is (508)

Why did it happen like this?. How do I get my solution?
 
Anybody know, please tell
Thanks in advance!

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
