ABS Function (DAX)
Returns the absolute value of a number.
The number for which you want the absolute value.
A decimal number.
The absolute value of a number is a decimal number, whole or decimal, without its sign. You can use the ABS function to ensure that only non-negative numbers are returned from expressions when nested in functions that require a positive number.
The following example returns the absolute value of the difference between the list price and the dealer price, which you might use in a new calculated column, DealerMarkup.
