# \dots alignment in math environment and amsmath [duplicate]

In some cases, with amsmath, it seems that the dots are not well aligned. For instance, when in parenthesis, it is normally aligned, but when followed by a colon, it is in the middle of the line.

MWE:

    \documentclass{article}
\usepackage{amsmath}

\begin{document}
$(\dots) = \dots:$
\end{document}


Which gives the following result:

• that is the whole point of \dots it chooses between \ldots and \cdots depending on the context, – David Carlisle Sep 5 '16 at 9:29
• Indeed egreg, somehow duplicate of the one you mentioned. But for my defence, if the title was more explicit than "how do magic \dots work in amsmath?", I would have saw it when I searched for "\dots alignment" ;-) (And for the sakeof completeness, the "\ldots" solution -which is exactly was I searched for- is only mentioned in a comment and not a full answer). – Bromind Sep 5 '16 at 10:00

\dots chooses between ldots (low dots) and \cdots (centered dots) depending on the context. You can always use the lower level commands directly if you do not like the choice it makes.

Or you can use the following semantically oriented dots versions (from the amsmath manual)

· \dotsc for "dots with commas"

· \dotsb for "dots with binary operators/relations"

· \dotsm for "multiplication dots"

· \dotsi for "dots with integrals"

· \dotso for "other dots" (none of the above)

• Ok, I didn't know the existence of \ldots. And now you mention it, it makes it logical. thanks ;-) – Bromind Sep 5 '16 at 9:38
