CONCATENATE (<text1>, <text2>) The CONCATENATE function can only accept two arguments as seen in the syntax above. You feed format a format string, "#0.0" will return a number to one decimal place. Converts a text string that represents a number to a number. Rather than the text being all capital letters as entered in the table, only the first letter is capitalized. The order of the calculation for the multiplications and the presence of a currency in the numerator of a division might produce different results because of the point in the calculation where the conversion is made. For example, if a column of values you import from Excel has no fractional values, Power BI Desktop converts the data column to a Whole number data type, which is better suited for storing integers. And for that we are going to use MID and then use it to add a new column to the previous variable. Although the starting number is identical, the calculation of the average price generates a decimal or a currency depending on the data type of the initial amount. If a required calculation sums most of the positive numbers before summing most of the negative numbers, the large positive partial sum at the beginning can potentially skew the results. I am taking data from the excel where there is a column "Global" with values as whole numbers and decimal numbers. You cannot place such measures as values for a bar chart.
