I would like to display numbers with a 0 before when there is only one
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/Fixnum.html, 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
