eqnarray or equation for single-line equations?

Use equation
for single line equations (or \[...\]
for unnumbered ones) and never ever use eqnarray
. See eqnarray vs align for more information.

Normally I would use
\begin{equation}
, of course. But I got a huge file (more than two hundred pages) where many equations are formatted like this:\begin{eqnarray} a = b + 1 % no & here! \end{eqnarray}
AFAICT the visual difference is minimal. Still, should I convert all this to
\begin{equation}
?(I suspect that the bigger problem might be the missing
&
characters around the=
. If I add them, I get exactly the same output as with\[...\]
, which should be the right thing.)I use the svmono document class, if that is important.

Reinstate Monica over 11 years@MarcoDaniel Thanks, but that question is about a list of related equations, which I don't have here.

bodo about 11 years@egreg: It seems to me your comment answers this question. Maybe you should put it as an answer!?!

Reinstate Monica about 11 yearsThis suggests that I convert all equations. However, the link and the documents linked from it and the answers do not seem to give any information for my specific question: single line, no alignment (i.e. no
&
). No source says anything bad (or good) about that (unless I missed something). So while your answer certainly is good general advice, I am not sure how it applies here. -
egreg about 11 years@WolframH If you don't want to edit your document, fine. But you'll do yourself a favor using the right environment for each equation or group thereof. This doesn't include
eqnarray
. :)
