Hi,

I would like to display numbers with a 0 before when there is only one
char.
For exemple if I gets the number 4, I would like to return 04.

After looking methods on
http://www.ruby-doc.org/core/classes/F..., I don't see how to
process. Of cours it is possible to convert a number into string and
after add a 0, but it's not very friendly.

Thanks for ideas

Dan's suggestion is the simplest. But I want to point out that you can
add a Fixnum method yourself, if you are so inclined:

class Fixnum
def to_formatted_s
"%02d" % self
end
end

puts 7.to_formatted_s

My Mom listened to him in the 60's, but as kids/teens they grew up
more with Sinatra, and Big Band stuff which my Dad loved. I was born
in 58. I would have been listening to The Beatles at that time. My
parent's didn't hate The Beatles. I remember my Dad also liked
Bohemian Rhapsody....OK next decade....but he like it.
