[racket] Filling number

Hi,

Looking for a friend of real->decimal-string (which does only partly what
you want), I see that the nightly builds include a family of value
formatters like ~a, ~v, etc.
You probably want ~r, for example:
> (~r 42 #:min-width 5 #:pad-string "0")
"00042"

They have many options that should fit your needs.

Cheers,
Laurent
