Power Automate Fundamentals # 30: Usage of Less Than Function in Power Automate


In Power Automate, generic arithmetic operations like Less Than will be used to validate provided integer values. As an example, an integer variable used to work with Less than 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, name flow as Less Than Function and take initialize variable and name it as Set Entry Level Age for Child Park Entry  to 5 with the following fields

Name :  Number

Type :  Integer

Value : 5

as shown in the below figure.

Step 4:

After Step 3, take compose action and name it as Check if Age less than 3  and provide

Inputs: less(value: integer|float|string, compareTo: integer|float|string)



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

Step 5:

After Step 4, take compose variable and name it Set the Check if Age  less than 7 and provide

Inputs :     less(variables(‘Number’),7)

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

Step 6:

After Step 5, run and test the flow and observe false and true values were written for the compareTo values which are 3 and 7 in Step 4 and Step 5  as shown in the below figure


  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 use Less than function so that basic comparison between integers in power automate can be done easily.
