UDP and float/double values Hi,
I've been working lately on a multiplayer module for a simulator, which
would require me to transmit 12 double values (96 bytes) as often as 10
times per second. Those values are needed in their full precision and
constantly change, so I can't dismiss them.
I know that passing directly float and double values can result in
unpredictable results, as there is no such thing as htons() for those
types. I would prefer not to transmit those values in a string format,
since it seems like a complete waste of bandwidth and precision.
Any suggestions?

Represent every float/double as 2x integers. One for the integer part
and one for the fractional part...?

Sure there are. Look up "htonf" and "htond". FlightGear, for
one, uses those.
