[comp.text.tex] Latex Help: Equation numbering format

llew@wpi.WPI.EDU (Lew Yan Voon) (04/08/91)

Hi

I need urgent help in redefining a latex format.
I need to use square brackets to enclose eqn no. instead
of ( ).
Can it be done in an easy manner, i.e., without having to
modify latex.tex or using tex?
i can solve the problem for single line displays by
using the tex command $$ .... \leqno[...]$$ but
$$\leqalignno{... $$ wasn't recognized by latex.

thanks,
lok.

Yes it can be done in an easy manner!  In the preamble area
(after \documentstyle before \begin{document}), put

\makeatletter
\renewcommand{\@eqnnum}{{\rm [\theequation]}}
\makeatother

This should do the trick.
