Aug 7, 2023 · a sequence of digits. The set of valid values for base is {0,2,3,...,36}. The set of valid digits for base- 2 integers is {0,1}, for base- 3 integers is {0,1,2}, and so on. For bases larger than 10, valid digits include alphabetic characters, starting from Aa for base- 11 integer, to Zz for base- 36 integer.
