Comment on Every base is base 10

  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.

    It’s because we count the 0… no? 0 and 1, base 2. 0123456789, base 10.

      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!

    (There is no 10 in base-10, which is why we construct it out of two other numbers)

  What is this “8” you refer to? Here in the land of people without thumbs, 10 comes after 7.

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

  What about unniftimal? (Base 37)

  source

  • NeatNit@discuss.tchncs.de ⁨5⁩ ⁨months⁩ ago

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

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

  every unsigned system is base -1 …or maybe -1+1
