OK, but for floats the situation could be more complex. On Intel,
the exponent/sign byte is the last one. Is it always the first
one on BE platforms ? If it isn't then using ntohl() or htonl()
wich are designed to work on 32-bit ints will not help. 

For doubles, things are even more fuzzy. Can you just use ntohl()
and htonl() on both halves, or do these two have to be swapped as
well ? Will either rule produce consistent results on all
platforms ?
