Read more, This article describes how to hide measures from a group of users by leveraging object-level security in Power BI and Analysis Services. Approximate data types have inherent precision limitations, because instead of storing exact number values, they may store extremely close, or rounded, approximations. This issue is most apparent when you use the RANKX function in a DAX expression, which calculates the result twice, resulting in slightly different numbers. It's recommended that you explicitly remove any binary columns as the last step in your queries. The third and last example computes an estimate, based on the average price computed using an amount stored in a currency or decimal data type. How do I solve this?

Here I have created a parameter table for the currency values. This change happens because Power Query Editor is case sensitive, so it shows the data exactly as stored in the source system. To start with, I created a test measure as follows. 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. You feed format a format string, "#0.0" will return a number to one decimal place. To summarize, when working with Boolean data in Power BI, make sure your columns are set to the True/False data type in Power BI Desktop.
