Issue with handling Decimal data Types

[Anonymous]

Hi,

I have 2 columns Value and qty both of decimal data type formats. In whole Data range maximum scale of value is 2 and for qty is 3. I have to calculate Cummulative of value and qty and divide them. for eg in my data qtys are like {2.454,234.56,0.01}, as maximum digits after decimal is 3 so when i sum it up result value scale should not exceed 3. In PowerBI when i check the sum its like 1.46E- 11, im not sure how is this possible. to avoid this in power query i grouped up with below mcode

= Table.Group(
#"Changed Type",
{"ID"},
{
{"value", each Number.RoundUp(List.Sum([Value]), 2), type nullable number},
{"Qty", each Number.RoundUp(List.Sum([Qty]), 3), type nullable number}

}
)

result values are 0.1 and 0 which is trustable. My question here is how to achieve this without grouping.

Please use the below drive link for the excel files and pbix used.

Attached images of source file and pbix file with both scenarios one grouped in power query and another table without grouping.

Try changing the column to fixed decimal type as the last step in Power Query. It's called Currency in Power Query and hast 4 decimal points. According to your description this matches with your requirements.

Thanks Martin,

To be surprised, even for Fixed decimal same results are thrown from PowerBI.
