Subject: Any guides for good coding in Ruby?

Is there some kind of class to format numbers? Something to let you
transform:

1	=>	"0001"
1234	=>	"1,234.00"

I needed to display the day and month in a 00 format and the way I did
it was adding a method to the Integer class

class Integer
	def addZero
		return "0" + self.to_s if self.to_s.length == 1
		return self.to_s
	end
end
t = Time.now
p "The date is: #{t.year}#{t.month.addZero}#{t.day.addZero}"

What do you guys think of this solution?


On a side note, could you guys give a few rules of thumb you follow in
order to make your code clean and readable?
