Hi Taro,
Probably racket/format is what you need to look at.
http://docs.racket-lang.org/reference/strings.html#%28mod-path._racket%2Fformat%29
#lang racket/base
(require racket/format)
(define (this-format num)
(~a #:min-width 3 #:align 'right #:pad-string "0"
num))
(this-format 5) ;=> "
Hi,
Please tell me the way of the following in racket?
In C,
printf("%02d", 2);
In Common Lisp,
(format t "~2,'0D" 2)
