      I’m not sure if you’re getting it, so I’ll explain just in case.

      In computer science a few conventions have emerged on how numbers should be interpreted, depending on how they start:

      • decimal (the usual system with digits from 0 to 9): no prefix
      • binary (digits 0 and 1): prefix 0b, so 0b1001110
      • octal (digits 0 through 7): prefix 0, so 0116
      • hexadecimal (digits 0 through 9 and then A through E): prefix 0x, so 0x8E

      If your zip code starts with 9, it won’t be interpreted as octal. You’re fine.

        Well, you’re right. I wasn’t getting it, but I’ve also never seen any piece of software that would treat a single leading zero as octal. That’s just a recipe for disaster, and it should use 0o116 to be unambiguous

        (I am a software engineer, but was assuming you meant it was hardcoded to parse as octal, not some weird auto-detect)

            Interesting that strtol in C does that. I’ve always explicitly passed in base 10 or 16, but I didn’t know it would auto-detect if you passed 0. TIL.

          It’s been a long time, but I’m pretty sure C treats a leading zero as octal in source code. PHP and Node definitely do. Yes, it’s a bad convention. It’s much worse if that’s being done by a runtime function that parses user input, though. I’m pretty sure I’ve seen that somewhere in the past, but no idea where. Doesn’t seem likely to be common.
