Is zero discrete?

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?

Quantized. I'll open a new thread from here on

It is a quantity. Correct me if its not that please.

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

I mean I can have zero of something

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'.

Like X.

What is X?

14. May 7, 2015

### Atlas3

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

You mean the variable X?

16. May 7, 2015

### Atlas3

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.
