    Octal is base 8. Decimal is base A. Hexadecimal is base G. Any questions?

      Jesus Christ.

      I just realized that we call binary base2 and there’s no 2 in that numbering system. We call hexadecimal base16 but there’s no 16 (at least not like we know it). But then why is base10 base10? We have a 10…but it’s not a single digit number.

      Why is this reminding me of Project Hail Mary?

        Every base has ten, but it’s made of two digits

        Binary 0, 1, 10 Ternary 0, 1, 2, 10 … Decimal 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 Hex 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E, F, 10

        Each has the right count of digits for its base before you go two-digit - binary has two (0, 1), etc

          more precisely, every base has 10, but it’s usually not equal to ten. ten is a fixed value, while 10 depends on the base. you still count normally (one two three four five), even in a base two system. you just write it differently.

            I don’t see the need to bring values into this, this is about the naming of number systems. We really have no more claim to ten being this many (…) than hexadecimal people have to claim ten has this many (…)

              10 as the first overflow of digits is not a clear vlaue, it depends on the notation because its base is unclear.

              Ten as the English word is 100% defined. The issue is we translate seamlessly between the word and number, but there really is no confusion when writing ten. 10 in hex has a different english word: sixteen.

              English number names are mostly decimal-based, but their values are still fixed. Ten isn’t the word for “the first time our number system overflows”, it’s an amount.

              So I disagree. Ten will always be (…) this many, because it’s an English word.

          The same is true for all bases. What we call base-4 in base-10 is 0123. In base-16 it’s 0123456789abcdef, where f is what we would call 15

        because then every base would be ‘base 10’

        That or the decriarchy has been normalizing the decimal counting system as the default one for far too long!

        If you have a problem with that you must also have a problem with the other two

        If there’s no agreed symbol for digit 37, you can call it Base 37A (or express it in another base of your choosing).

        In case the formatting doesn’t work, that A is supposed to be subscript
