Numbers that have small fractional values can sometimes accumulate and force a number to be slightly inaccurate. 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. When you go to the Data tab in Power BI after you load the data, the same table looks like the following image, with the same number of rows as before.
