I have tried these with but when I try to create a new "Bill" it shows an error "TypeError: float() argument must be a string or a number, not 'Float'"

total = fields.Float(string='Total', digits=(10, 2)) remaining = fields.Float(string='Remaining', digits=(10, 2) default=total)

    remaining = fields.Float(related=total, string='Remaining')
