Using varioref to add parentheses to equation numbers

The varioref automatically encapsulate equation numbers with parentheses when referencing. This results in

\vref{eq1}

producing (2.3) instead of just 2.3.

Load the varioref package in the preamble:

\usepackage{varioref}

and specify a format for the type of reference

\labelformat{equation}{(#1)}
