Measure with fixed decimal number shows a lot more decimal places

[Jan_Trummel]

Hello community,

I have the coumn Total price in my table Sales. It's fixed decimal number:

Now, I create a measure called Total sales:

Total sales = SUM(Sales[Total price])

I didn't changed the formatting for this measure. The number of decimal places is still set to Auto:

I create a report with a matrix and show Total sales per Customer number. And now you see a strange behavior: For customers 21 and 24, my measure shows more than 4 decimal places - like this: 9.283,79999999999999

Does anyone know why this happens? Fixed decimal number means, that there should be maximum 4 decimal places.

I would check the fields [unit price] and [quantity].  If you change those to Fixed Decimal Number, that should clear up the issue.

Hi @Jan_Trummel,

Since you are calculating Total Price by multiplying total other columns which are decimals, it is possible that you get more than a fixed a number of decimal places. To maintain consistency in your report, I suggest that you set the decimal places to 2 (or 4, whichever you want) instead of Auto.

Hi @Shaurya  and sorry for really late answer!

It seems like if Power BI would store the values not as fixed decimal numbers, isn't it? Or is it a display error?
