Percentage with 10 decimal places.

[masterswordz]

Can someone help me write a query to ADD COLUMN percentage data type with 10 decimal places?

First 3 columns came from raw data all in text data type.

1. ADD COLUMN = SUM(100-0)/100 (but the result should be in percentage with 10 decimal places
2. Compare Column C and D.

Error from Dump	Total from Dump	Percentage from DUMP	ADD COLUMN %	Compare C and D
0	100​	100.0000000000%	​	​
16​	999999​	99.9983999984%	​	​

Goal is, just to make sure that the computation from the DUMP data sent to me are giving accurate results.

In Excel formula, I could simply use =TEXT(A2,"0.0000000000%") but I don't know to make this work using PowerQuery.

Does this do what you want?

[FONT=Verdana,Arial,Tahoma,Calibri,Geneva,sans-serif]let
    Source = Excel.CurrentWorkbook(){[Name="Table3"]}[Content],
    data.Typed = Table.TransformColumnTypes(Source,{{"Error from Dump", Int64.Type}, {"Total from Dump", type text}, {"Percentage from DUMP", type text}}),
    accuracy.Tested = Table.AddColumn(data.Typed, "Accurate?", each Text.Format("#{0.0000000000}",{Number.FromText([Total from Dump])/10000})=Text.Format("#{0.0000000000}",{Number.FromText([Percentage from DUMP])*100}))
