how to do number to string suffix
===

As you know in ruby you can do 


    "%03d" % 5
    #=>  "005"

    "%03d" % 55
    #=> "055"

    "%03d" % 555
    #=> "555"

so basically number will have "0" prefix for 3 string places

just wondering is there possibility to do number string suffix in similar nice way ?
(please no if statements) 

    something 5
    #=> 500

    something 55
    #=> 550

    something 555
    # => 555
