Power Pivot Principles: The A to Z of DAX Functions – FIXED

19 December 2023

In our long-established Power Pivot Principles articles, we continue our series on the A to Z of Data Analysis eXpression (DAX) functions.  This week, we look at FIXED


The FIXED function

The FIXED function is one of the text functions which returns the text value after rounding a number to the designated number of decimals.  You may also specify whether the result should be returned with or without commas.  It has the following syntax:

FIXED(number, decimals, no_commas)

  • number: this argument is required and represents the number we wish to round and convert to text, or a column containing a number
  • decimals: this is optional.  It is the number of digits to the right of the decimal point and the default value here is two [2] if this argument is omitted
  • no_commas: this is optional.  It is a logical value.  If we put one [1], it will not display commas in the return text and will if we put zero [0] in this argument.  If this argument is omitted, it will return text including commas.

It should be noted that:

  • if the value for decimals argument is negative, the number will be rounded to the left of the decimal point
  • this function is not supported for use in DirectQuery mode when used in calculated columns or row-level security (RLS) rules.

Let’s consider the following example where we have the following TB_Sales table:

As we can see here, the SalesAmount column is displayed to four [4] decimal places and the number is right-aligned here.  We will write the following FIXED_Example measure:

FIXED_Example = FIXED(SUM(TB_Sales[SalesAmount]))

After we drag the OrderDate and the above measure in, you may be able to display something similar to the following:

In this picture, the OrderDate is identical to the source data and the SalesAmount here is left-aligned, with rounding to two [2] decimal places.
