Be very careful how you swap floats. They aren't like integer data types 
where the swapped representation can fit nicely into the same type. Not 
all swapped floats are valid floats, and you'll find that the bits will be 
messaged into a valid float, thus changing your value without telling you. 
You can only swap a float into an integer. You can't swap a float into a 
float.
