During a conversation in my proposed challenge in sandbox, there had been some objections about requirments in the challenge.
I want to entirely ban a usage of floating-point numbers in the challenge, but as turned out in the discussion, that must be only if the inputs are arbitrary-length integers.
Do major golfing languages such as 05AB1E, Jelly, APL, and Charcoal natively support arbitrary-length integers like Haskell's
Integer? Otherwise, my challenge will be very different from what I intended.
