And indeed perhaps the fact that newlib apparently /doesn't/ return an error
should be considered a bug too. Or perhaps newlib doesn't support hex floats
and regards it as a hex integer constant and just stops scanning at the
period, assuming it's part of the next field. I'll try and take a look
through the newlib source at the weekend unless someone on the newlib list
[Cc'd in] comments that this is intended behaviour.
