Correct arrow for mathematical limits

Question

I am currently using $$\phi(\varepsilon) \overrightarrow{ \varepsilon \rightarrow 0 }0 $$ for writing down mathematical limits. But I am not very confident with this notation, as the text under the arrow is far too huge displayed. Does anybody here have a better suggestion

For limits, it is advised to use \to ... in math mode of course. A little hint: Do not use $$...$$ but \[...\] instead. — , Apr 06 '14 at 15:40
ah, thank you. and how do you write some text under this arrow? — , Apr 06 '14 at 15:42
@user180097 However I would define something like \tendsto{x\to\infty} (more “logical”) to be something like \xrightarrow[x\to\infty]{}. — Manuel, Jun 22 '14 at 14:32

I have two versions, depending on what you perhaps need.

\documentclass{book}

\usepackage{amsmath}


\begin{document}
\[ \phi(\varepsilon) \xrightarrow[\varepsilon \to 0]{} 0 \]

\[ \lim_{\varepsilon \to 0} \phi(\varepsilon) = 0 \]
\end{document}

I prefer the \lim style, it is mathematical cleaner, but that is also a matter of taste.

Why should the minimal class be avoided – Manuel Apr 06 '14 at 15:49
@Manuel: I used an old template, but I know about the caveats of minimal ;-) – Apr 06 '14 at 15:51
I insist that the formula is:
\xrightarrow[ THE LIMIT ]{}.
