BibTeX, biblatex and biber ⇒ Referencing the number of a reference in the paper

[gammapoint]

This is a really basic question, and I'm embarrassed to say that I've been using LaTeX for 3 years without knowing it But better late than never.

Let's say I have a section in my paper like:

"The experimental data of Ref. 11 shows...."

How do I do this properly in LateX?

If I do something like
"The experimental data of Ref.\cite{ref_11}" then it could show up like

"Ref.[11]" or "Ref.^{11}" depending on how the style of the document. So how do I simply reference the number itself?

Thanks in advance!

Ahh, after a bit of searching I found it. \citenum{ref_11}.

Thanks anyway!
