The first output in the console is 40.4 and the second

If i change the NSLog(s) to "%f",[n floatValue] (and the second
likewise) the first is 40.400002 and the second is -40.400002.
Why does this happen?
This is mostly independent on the language in use.
Numbers like 40.4 don't have, in general, an exact binary representation.
