## Sorting numbers[edit]

Integers in this category are sorted according to matching **series numbers**.

**a** is the first digit of a given positive integer with n digits. The **series number** is:

**0**if n=1**a**followed by (n-1)**0**digits if n>1

__Example:__ 256

- first digit:
**2** - n=3, 2×
**0**digits:**00**

The **series number** is: **200**.

So, a page about number 256 (like **Category:256 (number)**) will be categorized as follows:

- [[Category:Integers|200 256]]

More generally, any page about an integer will be categorized as follows:

- [[Category:Integers|
**series number****number**]]

- I think it's much better to put them in numeric order. I mean, that's really the only way that makes sense, right? So that's why I made
`{{numbercategory}}`. All you need to do is add that template to top of the category and put the number in the 1st parameter (i.e. {{numbercategory|*number goes here*}}). This auto-categorizes, auto-sorts, and adds a little navigation box (and possibly more). If we ever want to reorder the list the later we can simply change the template.
