In some books and on the internet I occasionally find pure binary and binary on its own, is there a difference between these two terms? If so, can someone describe briefly what they are?
Is there a difference between pure binary and binary?
terminology;encoding scheme
I'm guessing here for lack of context, but I think the following distinction is reasonable.A binary encoding is anything that maps stuff to bit strings. There are many, including two's complement, IEEE float, ASCII, and so on.Pure binary probably refers to bland natural numbers written in base two, i.e.if $n_{(2)} = a_k\dots a_0$ then$\qquad\displaystyle n = \sum_{i=0}^{k} 2^ia_i$.
