I need the numbers of equations and brackets around to be in bold. Doing like this


only the number is produced in bold, how to bold brackets?

And second question. I want my references to equations also to be with bolded brackets automatically, how to do this?

Are you using the amsmath package? – Gonzalo Medina May 23 '12 at 17:16

You can redefine \tagform@#1 from amsmath.sty:




a = b.
As we see from equation~\eqref{eq:test}...

Thanks! I didn't even used \eqref{} for this, thought that it should be done like this [\ref{}]. – Pavasaris May 23 '12 at 17:32
@Pavasaris you're welcome! The advantage of using \eqref over \ref is that the former automatically supplies the declared format around the equation number. – Gonzalo Medina May 23 '12 at 17:34

The »mathtools« package can do this job for you.

% !TeX program = pdflatex
\usepackage{mathtools}   % loads »amsmath«
