It's not a 5 digit prime.

  0 is a digit. Apparently I have stumbled over an idiom of the prime-enthusiast community.

    I don't think the different usage is related to an individual group rather context, particularly when referring to numbers. E.g. 3 is a 1 digit number because that's the number of digits needed to uniquely identify 3. There are infinitely more ways to identify 3 the number with padded 0s but those aren't useful unless you're talking about combinations/sequences of groups of digits (like random numbers or PIN codes) instead of actual number values.

    I don't think it's specific to "the prime-enthusiast community". Most people would look at you oddly if you claimed that 3 is a five-digit number.

      On the flip side, many people here would claim that 0x00000003 is an eight digit number.

        Only to win an argument by nitpick golfing. In everyday serious conversation that’s a 4-byte number, not an 8-digit number.

    I agree -- maybe technically not a digit, but I'd argue it's a UX issue if it is allowed in the leading slot. But I still love the concept!
