Power Automate Fundamentals # 18: Usage of Subtraction Function in Power Automate

Power Automate Fundamentals # 18: Usage of Subtraction Function in Power Automate

 

Introduction:

In Power Automate, at times we need to perform Subtraction arithmetic operations so that we can get easily desired result. As an example, let us see how to calculate warranty period that is available in years for Generator with the help of Subtraction 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 Subtraction Function and take initialize variable action and provide step name it as Initialize Variable to Hold Generator Age(1 Year) and then provide the inputs as in one side

Name : Generator Age

Type : Integer

Value : 1

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 Initialize variable to Hold Generator Warranty Period (5 years) and then provide the inputs as in one side

Name : Generator Warranty Period

Type : Integer

Value : 5

as shown in the below figure.

Step 5:

After Step 4, now take compose action and name it as Calculate Remaining Generator Warranty Period in Years and provide the following inputs as below with div function and it expects the following syntax

sub(minuend: number, subtrahend: number)

and provide

sub(variables('Generator Warranty Period'),variables('Generator Age'))

and click on update/ok 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 Subtraction to achieve simple requirement in Power Automate flow.
