Its hard to tell if you are talking about equation arrays with one equation or an equation that doesn't line-wrap and so takes only one line.

I can do you an environment that's uses equation if it has one entry and equation array if it has more than one.

But it won't take into account line wrapping.

Hello list,

I have a simple question:

Is there any reason not to use only one equation environment - the equation array?

As I see it, the only difference between an equation and a one-line equation array is the spacing around the "prominent" binary relation (the one according to which alignment happens in eq. array with more lines). I Imagine it would be possible to do the following:
1. IF there was only one line in an equation array, THEN the rendering would be the same as if equation had been used.
2. ELSE use the standard equation-array rendering.

Am I missing something? I find it inconvenient to have two different eq. environments. When writing an equation, I seldom know whether it will end up being a one-line eq., or not (will it fit one line or not?). Therefore, I mostly choose the eq. array environment, which is not spaced nicely if my equation ends up fitting just one line (with more binary relations).

Any thought on this?

Cheers,
Peter.
