But its precision may also be greater than that of long double on the
host, if long double on the target has greater precision than long double
on the host. Likewise, its range may be greater than that of long double
on the host. So it would seem a lot more sensible just to produce a hex
float value in your output without going through any decoding process at
all (but if you do decode, host floating-point types should not be
involved).
