**How can I customize equation numbers produced by **`\ref?`

Thanks to Rahul Bharadwaj for the question.

All of the following commands go in the preamble---that means between
the `\documentclass` and `\begin{document}` commands.

If you want to use parentheses around all equation numbers use

\usepackage{varioref}
\labelformat{equation}{(#1)}

If you want to use "equation (#)" everywhere, where "#" is the
equation number use

\usepackage{varioref}
\labelformat{equation}{equation~(#1)}

If you want to use some styles in some places and some in others
don't use add any extra commands to the preamble and use

` ` | **Input** | **Example Output** |

| `\ref{label}` | 1 |

| `(\ref{label})` | (1) |

| `equation (\ref{label}) ` | equation (1) |

Multiple commands can be defined to do different types
of equation number customization in the same document
but that is beyond the scope of this document.
