In mathematical numeral systems, the radix or base is the number of unique digits, including zero, that a positional numeral system uses to represent numbers. For example, for the decimal system (the most common system in use today) the radix is ten, because it uses the ten digits from 0 through 9.

Why is it that parseInt(8,3) == NaN and parseInt(16,3) == 1?
I'm reading this but I'm confused by what is written in the parseInt with a radix argument chapter
Why is it that parseInt(8, 3) → NaN and parseInt(16, 3) → 1?
AFAIK 8 and 16 are not base-3 numbers, so parseInt(16, 3) should return NaN too

What is the radix parameter in Java, and how does it work?
I understand that radix for the function Integer.parseInt() is the base to convert the string into. Shouldn't 11 base 10 converted with a radix/base 16 be a B instead of 17?
The following code prints 17 according to the textbook:
