Google tells me to use Format function, but I've tried it in vain. =IF("12"=12,"Expression is true", "Expression is false") returns "Expression is false". Indeed, in a complex expression there could be many operators, but every operator defines a single expression that produces a new data type that is the argument of the next operator. This type corresponds to how Excel stores its numbers, and TOM specifies this type as DataType.Double Enum. Thanks for the response. For example, depending on the configuration of your relationships, you might see an error similar to the following image: In other situations, you might be unable to create a many-to-one or one-to-one relationship because duplicate values are detected. The highest precision that the Decimal number type can represent is 15 digits. It would be more intuitive if all the results were decimal, or at least currency. To avoid unexpected results, you can change the column data type from Decimal number to either Fixed decimal number or Whole number, or do a forced rounding by using ROUND. In Power Query Editor, the resulting data appears as follows. Thanks. In power query, i want to insert a conversion from text to number (to delete zero in the beginning) in this formula, = Table.AddColumn(#"Lignes filtres1", "idbat-HH", each if Text.Contains([RS], "GRAND DELTA HABITAT") then "VL"&[EXTRACT_IDENT_INT] else null), = Table.AddColumn(#"Lignes filtres1", "idbat-HH", each if Text.Contains([RS], "GRAND DELTA HABITAT") then "VL"&NumberFromText([EXTRACT_IDENT_INT]) else null), = Table.ReplaceValue(#"idbat-ER",each [EXTRACT_IDENT_INT],each if Text.Contains([RS], "GRAND DELTA HABITAT") or Text.Contains([RS],"AXEDIA") then Text.TrimStart([EXTRACT_IDENT_INT],"0") else [EXTRACT_IDENT_INT],Replacer.ReplaceText,{"EXTRACT_IDENT_INT"}). You cannot place such measures as values for a bar chart. A good idea in theory, but not a good practice to have different names in different products using the same language. So it's important and useful to use the correct data types for columns. The same process happens for the remaining rows. Since the engine is case insensitive, "TAINA HASU" and "Taina Hasu" are the same. Returns the number of the character at which a specific character or text string is first found, reading left to right. Returns a string of characters from the middle of a text string, given a starting position and length. This can generate some confusion, as we will see in the next section. For the fourth row, the engine compares the value against the names in the dictionary and finds the name. For example, if a subtraction operation uses a date with any other data type, DAX converts both values to dates, and the return value is also a date.
