How about incorporating the % printf formatter directly, like ${var@%f} for
the locale-independent format and %{var@%#f} for the locale-specific format?
However any formatting done as part of the expansion assumes that the
variable holds a "number" in some fixed format, rather than a localized
string.
Personally I think this would actually be a good idea, but it would be
quite a lot bigger project than simply added FP support.
