To whom it may concern, My name is Yi-Ming Chang, I am writing this email to double check whether that is a bug in Python. [cid:image001.png@01D82E58.D5F1E830] I have searched online, they said this is binary float, but I am not is this an error in Python? Or there is a way to avoid it? Cheers, Yi-Ming
