In my school in Europe we learned that -1 is first negative number. But in programming one can define new context. When it says in documentation ARG is positive (ARG > 0) it give definition what it means in that specific context and so I understand it and use in that definition. Dictionary says: 9. positive -- (greater than zero; "positive numbers") Definition not necessarily need to be related to mathematical comparisons. While 0 may be positive in comparison to negative numbers it is definitely practically not positive as if there is nothing, there is nothing. If you have one apple you have the apple, if you don't have it is not there. There are different concepts.
