In C you can certainly get access to the binary representation of a 
float as bytes. My C is really rusty but something like
float x = 1.3;
char* p = &x;

will give you a pointer to the binary representation of x. You can do 
something similar with the struct module in Python; struct.pack() will 
give you a byte string containing the representation of a float.
