It sounds like this is not a change that we want to make, so I'm closing
this now.

Nevertheless, thanks for the patch, Vladislav.

I am not sure if this is intended behavior or not, but as it's just a
small change I am directly submitting a patch.

I would expect c-mode to treat numbers with a decimal point as one
symbol instead of two separate.  The same thing can be said about
designated initializers (i.e. {.pi = 3.14}).  I quickly checked the
behavior in emacs-lisp-mode and it works as I would expect there
(forward-symbol skips a decimal point number as a whole).
