The function (??) base^^

^^ isn't a function. It's a syntax. Just as 2. means "the numeric version of 2" and not the integer, 16^^ab means "the number 171". This is handled by the parser, not the interpreter which is why FullForm[Hold[16^^A]] is Hold[10]. Howver, and as was said before, FromDigits is likely what you want.

Hi,

The only function I know about that does what you are looking for is FromDigits. For example

Map[FromDigits[#, 16] &, {"a", "b", "d", "f", "1A2C"}]

I do not know why the function ^^ does not work in your Map example. I would be also interested in reading the reason.
