Needs some work yet tidying it up and making it rigorous before it can be POTWed. --prime mover 08:05, 13 July 2012 (UTC)

## nonstandard notation

Why does this article use nonstandard notation for open intervals? In one place \[ (a \,.\,.\,b) \, \] appears, and in another \[ (a..b) \, \] appears without even any spaces between the dots. Standard notation is \[ (a,b) = \{ x : a<x<b \}. \] Michael Hardy (talk) 18:00, 30 December 2012 (UTC)

- I would remind / inform you that MathJax does not like
`\( ...\)`

tags - they are deprecated. Please use`$ ... $`

to delimit your $\LaTeX$ instead. - In defence of the fact that sometimes there are pages with $\left({a..b}\right)$ in them is a shortcoming which we are gradually working on. As we spot them we replace them with $\left({a \,.\,.\, b}\right)$. Thank you for alerting us to this one.
- Concerning the notation, I refer you to Definition:Real Interval/Notation. I also refer you to Help:FAQ#I don't like the notation. --prime mover (talk) 20:11, 30 December 2012 (UTC)
