Power Pivot Principles: The A to Z of DAX Functions – DIVIDE
6 June 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 DIVIDE.
The DIVIDE function
The DIVIDE function is one of the mathematical and trigonometric functions. It performs a division and returns the result or BLANK() on division by zero (#DIV/0!). It has the following syntax:
DIVIDE (numerator, denominator, alternate_result)
It has three  arguments in the syntax:
- numerator: this is required, and it represents the number to divide (i.e. the numerator)
- denominator: this is required, and it represents the number to divide by (i.e. the denominator)
- alternate_result: this is optional, and it represents the value returned when division by zero results in an error. If this argument is not stated, it will be set to a BLANK value as a default.
Here are a few remarks about this function:
- the alternative_result on divide by zero (#DIV/0!) must be a constant
- the DIVIDE function is faster than an IF statement checking whether the denominator is zero , but the DIVIDE function is executed in the formula engine, and therefore it is not as fast as a native division.
Here are two simple examples of this function:
This will return:
Now let’s see the effect of dividing by zero :
Which will return the string: “Infinity” as we specified in the alternate_result argument.
