Power Automate Fundamentals # 16: Usage of Div Function in Power Automate

Introduction:

In Power Automate, at times we need to perform division arithmetic operations so that we can get easily desired result. As an example, let us see how to calculate price of a candy for quick reference from a bundle cost with the use of div function.

Step 1:

Login to the required Power Apps environment using URL make.powerapps.com by providing username and password and click on Flows on the left-hand side as shown in the below figure.

Step 2:

After Step 1, Click on New Flow and select instant cloud flow and provide the trigger as Manually trigger a flow and click on Create as shown in the below figure.

Step 3:

After Step 2, Add a parallel branch and in one part name flow as Division Function and take initialize variable action and provide step name it as Total Candies  and then provide the inputs as in one side

Name : Candies

Type : Integer

Value : 12

as shown in the below figure.

Step 4:

After Step 3, in other side of parallel branch take initialize variable action and provide step name it as Total Cost of Candies  and then provide the inputs as in one side

Name : Total Cost

Type : Float

Value : 1200

as shown in the below figure.

Step 5:

After Step 4, now take compose action and name it as Price of Each Candy and provide the following inputs as below with div function and it expects the following syntax

div(dividend: number, divisor: number)

and provide

div(variables('Total Cost'),variables('Candies'))

and click on update/ok as shown in the below figure.

Step 6:

After Step 5, now test and run flow and observe final result

as shown in the below figure.

Note:

1. Make sure to save and run the flow whenever you try expressions.
2. MS documentation is found at here

Conclusion: In this way we can easily perform arithmetic operations like Division in Power Automate flow.

Hi,

div(dividend: number, divisor: number)

In my case, dividend number is 4 and and divisor is 8. The expected result value is 0.5, but PA is returning 0 (zero). Is there any reason or is it a bug ? I'm using both values in variables

Here is the expression I used.

div(int(outputs('Total_projects')),int(outputs('project_committed_one')))

The function is working fine if the dividend value is greater than divisor. 

Can you please guide here?

@Niraj466 I had this also, but inconsistently. After some trial and error, it emerged that at least one of the numbers in play must be a float. Presumably this puts the div function into 'accurate mode', rather than rounding down? In your scenario, 

div(float(outputs('Total_projects')),int(outputs('project_committed_one')))

might work.

Hi @Niraj466  : Try with float type conversion instead of int, you should get 0.5 , if you use int you get as 0. Hope it helps
