Being further pedantic - aren't all digits base ten? I thought that was part of the definition of digit.

Other bases would have different words for their numbers - bit in binary, for example (which, yeah, I know, it a combination of the words "binary" and "digit").

If you really want to be pedantic, you say that every base is base 10 :) (in its own representation)

Do we have another example? I don't think there are special terms for "octal digits" or "hexadecimal digits".

We call computer circuits "digital" even though they work in base 2.

Regardless of the word's origin, digits are simply the symbols in a positional number system: https://en.wikipedia.org/wiki/Numerical_digit
