Integer in hex notation?

[LunatiX]

How can I change the notation of a Integer value, t.e.:

(Integer -> hexadecimal notation)

Two possible ways:
1. Have the value stored/converted in the PLC already
2. Convert it using a LocalScript that subscribes to the item, converts it to hexadecimal and emits it as a virtual item that will then be connected to the desired widget

There is another way, with the iq-text element which support the execution of JS functions.

1. Define a Local-Script "Globals" where you can place all your global JS functions, variables and constants.
2. Remove code, which is automatically created
3. Insert code
   

   /**
   Converts an interger number to a HEX string
    * @example
    * x = Int2Hex(255, 4)); // x = "00FF"
    * 
    * @param {number} iVal Number to convert
    * @param {number} iLen length of converted string
    * @returns {string} HEX string of iVal
    */
   function Int2Hex(iVal, iLen) {
       return iVal.toString(16).toUpperCase().padStart(iLen, "0");
   }
   
   /**
    * Converts iVal into binary string
    * @example
    * x = Int2Bin(3, 4)); // x = "0011"
    *
    * @param {number} iVal Number to convert
    * @param {number} iLen length of converted string
    * @returns {string} HEX string of iVal
    */
   function Int2Bin(iVal, iLen) {
       return iVal.toString(2).padStart(iLen, "0");
   }

4. Insert a iq-text with the INT item to display as HEX number
5. Not working with virtual items
6. To display Hex: Insert text: <%= Int2Hex(items[0].value,6) %>
7. To display Bin: Insert text: <%= Int2Bin(items[0].value,6) %>

Thank you for this function !   I just used it. Works fine.

I had some troubles first because I used the wrong iq-text...

Therfore for beginners like me 🙂
