Can I send a float from one Machine to another as Raw Bytes?

Yeah totally fine, it's just when you go from a processor that is one endian and send to another that you have to worry.

there is something called "network byte order" that you can use for all your communications, and then put everything into the right byte order on the client side.

but meh, yeah for your purposes it's fine to just send it raw yep.

If you want to learn more about this stuff try googling these terms:

Big endian
Little endian
network byte order

Good luck!

Thanks
