R5RS says: If the written representation of a number has no exactness prefix,
the constant may be either inexact or exact.  It is inexact if it contains a
decimal point, an exponent, or a "#" character in the place of a digit,
otherwise it is exact.

Yes, it expresses that -1. is inexact number.

If you test it with currently uploaded draft, you will see the following.
Error: fmt: bad argument
       (10)
       str-list
       (not (every string? str-list))
This means the 10 must be a string.  FMT has only 2 numeric optional
arguments, that is, <width> and <depth> or <width> and <count>.

(fmt 1/2 5 2 #\space (fmt 10))           " 0.5010"
(fmt 1/2 5 2)                            " 0.50"
The default value of padding character is #\space.

Thanks
