Add zero to the left of Integer

Question

I want to add a certain number of zero to the left of an integer number and save it to an Integer rule input..I was using text(value,"0000") this function which gave me exact format but when I save that to an Integer variable , all zeros had been removed. 
 Id type is Number(Integer) for ref: 
 { a!textField( label: "Text", labelPosition: "ABOVE", value: text(tostring(ri!Id), "0000"), saveInto: ri!Id, refreshAfter: "UNFOCUS", validations: {} ), a!buttonArrayLayout( buttons: { a!buttonWidget(label: "save", style: "OUTLINE") }, align: "START", marginBelow: "NONE" ) }

If you want to display leading zeros, I would suggest using a textfield. You can use a regex function to validate that all characters are numbers. Otherwise, tointeger on the onSave will just strip the non-integer values.

 It's not possible , Just like others suggested the only two possibilities are 
 1. Changing the data type of the field to string 
 2. On interface level show it in a text field by adding the zeros .

To clarify, integer (the data type) does not understand or care about "leading zeroes". "0001" is not a distinct integer from "1", both have a value of "1" (stored deeper in the system as the binary representation fo the number "1" moreover). 
 What you're asking for here is display formatting, for which (as others have mentioned) you'd use text and various rules/functions to format its displayed value, and/or you could store a literal representation of the displayed format you're after into a text field. 
 But what you need to understand most is that these are completely different things - otherwise you're gonna have a hard time with coding anything in Appian.

Hello prashamas6791 , I think it is not possible because if it is an integer field, then it won't accept this format because it will remove all the zeros before the ID.
