Subject: Newby question 'unless'

Hi all, I'm overriding to_s method and I want to
print an attribute if a condition is fulfilled.

def to_s
   "#{@a}" + "#{@b}" unless @a == 0
end

That sentence doesn't print anything when @a == 0 but what I want to do
is to not print @b when @a == 0.

What's the correct syntax?

I know I could do:

     def to_s
         s = "\n#{@post}"
         if @post != :GK
             s += "#{@side}"
         end
         s
     end
