I don't understand this.

AFAIK you can not get this with the spec-string to `interactive', but
there is nothing wrong with an explicit call to `read-from-minibuffer'
in this case.
(read-from-minibuffer "Hello: " (number-to-string 5))
The return value is a string. I only glanced quickly over this thread
(sorry for this!), but I seem to recall that someone already told how
to check if a string contains the decimal representation of a number.
To repeat this until the input is a valid number, use `while'.
[untested:]
(while (not (string-match
"^[-0-9]+\\(?:\\\\.[0-9]\\)*$"
(setq my-number
(read-from-minibuffer "Hello: "
(number-to-string 5))))))
... or something less cluttered ...

I can not parse this.
