    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'.

    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.
