How to add quotations around numbers in Vim - Regex?

Question

I have been trying, unsuccessfully, to add quotation marks around some numbers in my file using regex. To clarify, let me give an example of what I am trying to do.

Something like myFunction(100) would be changed to myFunction("100").

I thought :100,300s/\([0-9]*\)/"\0" would work but it put quotation marks around spaces as well.

What can I do to fix this?

You should slightly modify the regular expression:

%s/\(\d\+\)/"\1"

In regular expression, first matched group is \1, not \0. And it looks safer to use \+ instead of *.
