Thanks to Sean Fiene for assistance.
Question: I would like to input a number into a “Single Line Textbox” and have the results show only two decimal places on the View mode of the form.
Create a Nintex Form and add a ‘Single Line Textbox’ configured with a Data type of ‘Decimal’ and name of “RoundNumber”
Add a rule of type “Formatting” with a condition of “Is display Mode” and “Hide”
Formula builder for condition:
Under Nintex Forms Ribbon bar choose “Form Variables”
Click ‘Add’ and create a new variable that includes a formula of ‘Round’ referencing the single line text column of “RoundNumber” and the number of decimal places needed.
Example: Round(roundNumber, 2)
Add a calculated Value control to the form with formula referencing the Forms Variable you created in step 3, in my example it is named “Rounding”.
Create a rule on the Calculated Value Control with formatting condition of “not(Is Display Mode” and choose ‘Hide’
Align the Single Line Textbox and Calculated value controls on top of each other and publish the form.
