However, with decimal values, translating those distinct values to a binary representation, sometimes a simple representation in decimal does not translate perfectly to binary.įor example. Integers are easy, by just adding or subtracting one whole number, you can do the same with binary data: For example, an original value of 40.48 would be correctly rounded to 40.5 if one decimal place were specified and 40 if zero decimal places were specified.ĬauseTableau Desktop (Tableau Prep) rounds numbers based on the original value in the database, following the "round up by half" convention.Īdditional InformationAs this behavior is not specific to Tableau Desktop, it is more fundamental to how computers store data, specifically what we consider "decimal" values. View the underlying data to verify the original number to ensure that it is being rounded correctly for the number format. Please note that such modifications can create a long and not very performant calculated field: STR(ROUND(SUM),2) = 319.147230000001.Use additional string modifiers such as LEFT() as well as additional rounding tools such as CEILING() to create a more accurate representation.

To view a concrete example, please see the attached workbook called Round String.twbx. To fix this behavior, rewrite the above calculation example as follows: ROUND(SUM(Field)) However, the aggregation must be considered when writing the calculation as Tableau may interpret the calculation relative to the aggregations applied. For example, if the field needed to round is SUM() and the calculation implored is ROUND() then Tableau will interpret said calculation as SUM(Round(). Rounding may be accomplished in Tableau Desktop with the ROUND() function. For example: STR(ROUND(SUM),2) EnvironmentTableau Desktop For example, a number displayed as 40.5 might change to 40 when the formatting is changed to show zero decimal places.Īdditionally, when you use ROUND() within a STR() function, the rounding might be incorrect when connected to an extract. IssueWhen adjusting the number of decimal places shown for a number, numbers might appear to round up or down incorrectly.
