Hello,
I'm currently new at this and any form of coding language. I've been searching online about the answers and stuck.
Could someone teach me how to simply change a Dec Output number to Hex ?
Thank you.

Do you really want HEX as in a hexadecimal string?
Do you expect this to be encoded with `0x` prefix?
did you look at the built examples in the FINS node...
... there are some good examples of data conversion in there.

Also, here is a demo you can import and play with...
