The set of integers includes negative integers as well as positive integers. It also includes the number zero which is neither negative nor positive.
A decimal can be a positive integer or a negative integer or neither of the above. For example: 26.0 is a positive integer. -52.0 is a negative integer. 26.2 is not an integer at all. 0.0 is an integer, but is neither positive nor negative.
Zero has no numerical value,therefore it is neither positive nor negative.
Zero can be included in the sets of non-positive integers or non-negative integers but it is neither positive nor negative. It's nothing. Literally.
Positive and negative whole numbers and zero are integers. Zero is neither negative or positive.
9 and 17 are. Zero is neutral, neither positive nor negative.
The set of natural numbers (counting numbers) {1,2,3,4....} corresponds to the positive integers. Note that the number 0 is neither positive nor negative. So anytime you want to count something you use natural numbers, which means you are also using positive integers.
