How to auto bracket ( ) referenced math equation numbers?

Question

For example, a math equation is labelled using \label{my_equation}

Then I refer to it later using \ref{my_equation}

However, what I get is just a number say 11, instead of what is more mainstream which is (11) i.e. the equation number with brackets around it

Do I must put brackets manually every time or is that some way to hard code this?

Just think you could have been saved typing () by typing an extra eq each time: a massive saving:-) — David Carlisle, Sep 14 '16 at 19:54
@BeachedWhale You can easily do a search and replace with regular expressions: search \(\\(ref\{.+?\})\) replace \\eq\1. — Manuel, Sep 14 '16 at 20:22

\eqref from amsmath adds () automatically.

More generally it adds whatever punctuation has been specified to be used in the label, so consistency is maintained even if you change the style.
