doing ``isinstance(obj, Number)``.
Numbers are further divided into :class:`Exact` and :class:`Inexact`.
Exact numbers can represent values precisely and operations never

commutativity and associativity properties; inexact numbers may

integers, and rational numbers are exact, while floating-point
and complex numbers are inexact.
:class:`Complex` is a subclass of :class:`Number`. Complex numbers
can undergo the basic operations of addition, subtraction,
multiplication, division, and exponentiation, and you can retrieve the
