A number's radix (also known as its base) is the number of unique digits used in its representation. Common examples are binary (base-2), octal (base-8), decimal (base-10), and hexadecimal (base-16). Use this tag for questions about converting between or otherwise manipulating numbers with different radices.

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

Can I create a base template for my project which all apps can draw from? Or do I have to create a base template for each app? And if I wanted them to be the same I'd just copy them?
