Column values of Decimal number data type are stored as approximate data types, according to the IEEE 754 Standard for floating point numbers. To avoid unexpected results, you can change the column data type from Decimal number to Fixed decimal number or Whole number. For example, if an addition operation uses a real number in combination with currency data, DAX converts both values to REAL and returns the result as REAL. The corresponding data type of a DAX decimal number in SQL is Float. Syntax DAX CONVERT (<Expression>, <Datatype>) Parameters Return value Returns the value of <Expression>, translated to <Datatype>. In Power Query Editor, the resulting data appears as follows. Auto-suggest helps you quickly narrow down your search results by suggesting possible matches as you type. ) [RegionID]) & " " & table1. For example, if a division operation combines an integer with a currency value, DAX converts both values to real numbers, and the result is also a real number. You can than perform some transformation to get the correct value value out of them. As with the Fixed decimal type, the Whole number type can be useful when you need to control rounding. The currency data type is important to avoid certain rounding errors in aggregations, but it should be managed carefully to avoid other types of rounding errors in complex expressions. The product (*) operator returns an integer when two integers are involved, and it returns a currency when a currency and a non-currency type are involved. What do you mean by "doesn't work"? Find out more about the February 2023 update. This is the output of the SplitString variable: Now what we will do is extract numbers from the @Single Character Column and for that we will have to do some complex operations, The first thing we will do is add another column to the SplitString variable and name it as "@String to Numbers" this column will have a nested variable, The first variable CurrentCharacter gets the value of the [@Single Character] in the currently iterated row supplied because of the row context created by ADDCOLUMNS, Then the IF function in the Result variable checks if conversion of the CurrentCharacter to numeric result in error or not, if it is not an error then do the conversion and we simply store the value else return BLANK. If you add values in two columns with one value represented as text ("12") and the other as a number (12), DAX implicitly converts the string to a number, and then does the addition for a numeric result. In order to detect the cell(s) that have the problem use the following code then look for the blank cells: IFERROR (VALUE (Sheet2[Size Value] ), BLANK ( ) ). This is important.

Here is a good detailed guide about it; Now the FORMAT function can be combined with some other methods to make the dynamic formatting a possible option. When you load a column with these data types into the Power BI model, a Date/Time/Timezone column converts into a Date/time data type, and a Duration column converts into a Decimal number data type. If so, how close was it? For the fourth row, the engine compares the value against the names in the dictionary and finds the name. ncdu: What's going on with this second size column? Context Transition. These functions are known as Text functions or String functions. if you really want to have the value as the $ or amount or quantity and %, then Tabular editor gives you better options for it.

There is a difference between Result1 and Result2, caused by the order of the multiplications. It would be more intuitive if all the results were decimal, or at least currency. The only change that we need to make in the code that we have written so far is that instead of specifiying an explicit string in the CurrentText variable we are going to let the row context do the Job, so instead of writing.
