Just to note. Depending on how many of these you're sending over the
link, I think having an NSData for every 4 byte float is a bit
overkill and could probably end up being a bottle neck. I'm not
saying you should optimize early, but there might be a more straight
forward way of creating a float out of the raw data than first shoving
it into a data then some other object and then finally outputting it
as a 32-bit float.

I have a case where I'm sending IEEE 754 32-bit floats to my Cocoa
program over a wireless serial link, they are being sent MSB first.
I'm using AMSerialPort to handle my data, and after a little
parsing, I'm left with a 4 byte NSData, which has the 32-bit float
split into 4 bytes.
I know I have to play around to make sure the bytes are in the right
order. But what I can't seem to figure out, is how I create a float
from those 4 bytes stored in an instance of NSData. Has anybody run
into this situation?_______________________________________________
