I hadn't been following the thread, and have only just now seen
Simon's email.  Sorry to gang up on you.  :)

I think what I'd be inclined to do is print your WebAssembly floats
and doubles in %a format.  You can probably do that without converting
to host doubles.  If that idea doesn't fly, just use a constant
specific to your target floats and doubles, hoping the host is
reasonably compatible.
