    I would think that any single object is "discrete", but perhaps I am using a different definition of "discrete".
    What definition are you using?

    Zero is a real number too!
    Anyway, I think the question is meaningless. Discreteness isn't a property of a single number!

    I have a simple counting question and the use of decimals. Possibly I want to count decimal fractions differently for the purposes of defining the range of something. A different number line of a kind? Folded eventually. Does this seem like a practical forum to ask this type of question?

    Yes, just open a new thread for your question.

    What is a quantity? If you mean discreteness, then no, its a concept!

    You started by asking 'Is 0 discrete'. I asked what definition of 'discrete' you are using and you responded "quantized". That is a term used in Quantum Physics and is meaningless here. Now you are asking whether '0' is a quantity. Yes, if you ask a store owner, "how many boxes of cigars do you have", the store owner could well answer, 'none'. '0' is definitely a 'quantity'.

    I mean like a algebra teacher refers to the quantity X.

    You mean the variable X?

    Yes but not variable Zero

    Zero is not a variable -- it is a constant, just like 1 or 5 or -213.7 or ##\pi##. A variable can represent an arbitrary number*. Zero is a very specific number.

    * - My context here is elementary algebra of the real number line, so I'm not considering variables outside that realm.

    i didn't state varied zero. Constant zero. I wasn't being funny

    You said "variable Zero" in post #16, which I quote again, below. How else was I to interpret "variable Zero"?

    Perhaps you could tell us what are studying and how you came to asking about zero being discrete.

    Every time you are asked to clarify something, you answer with another ambiguity. I am starting to think that this whole thread was just a joke. Your original question was "Is 0 discrete?" I asked what you meant by "discrete" and your response was "like X". Please tell us what you think the word "discrete" means!

    I'll try. If I can figure out the forum post editor for markup when I get the time on a computer right now it is cumbersome on iphone

    Whatever.
    What you said was extremely unclear. I have no idea what you're trying to say with "not variable Zero".

    Back to the original question, "Is zero discrete?" A set of numbers that is separated is discrete, such as {0, 1, 2, ...,n, n + 1, ...} or {1/4, 1/2, 3/4, 1, 5/4, ...}. I'm not sure it makes any sense to talk about a single number as being discrete.

    I was asking if zero is considered a discrete value meaning nil but countable. Wasn't asking a philosophical question or making a joke. Just asking if in numbers it is considered the same as any other. Discrete was the answer I received. And thanks the poster for the immediate answer.
