@PeteBlackerThe3rd is 100% right, you should probably create your custom message as explained in the tutorials.
Nevertheless, just __for your information__, ROS use the Boost Serialization library. May be you want to learn how that work to do your own serializations...
If you are not worry about indianess (and usually you should), serializing a double is as easy as using __reinterpret_cast__
double val = 3.14; uint8_t buffer[sizeof(double)]; //serialize memcopy( buffer, reinterpret_cast<uint8_t*>(&val), sizeof(double) );
//deserialize double val2 = *( reinterpret_cast<double*>( buffer ));
