Open [HELP] Get enodeb value

Hey guys, i know that enodeb value comes inner CellIdentity, but i need to make some coversions in order to get the value and there's where i need help.
Someone please can tell me how:
1 - convert the variable from dec to hex (DONE)
2 - ignore the last two digits from the converted value
3 - convert back to decimal

How the heck i can do that in tasker? The "Variable Split" needs some kind of args and i don't know how to use the length of the variable to ignore the last two digits
