all, and only exists to allow checking if an object is a number by all, and only exists to allow checking if an object is a number by
doing ``isinstance(obj, Number)``. doing ``isinstance(obj, Number)``.
Numbers are further divided into :class:`Exact` and :class:`Inexact`.
Exact numbers can represent values precisely and operations never
round off the results or introduce tiny errors that may break the
commutativity and associativity properties; inexact numbers may
perform such rounding or introduce small errors. Integers, long
integers, and rational numbers are exact, while floating-point
and complex numbers are inexact.
:class:`Complex` is a subclass of :class:`Number`. Complex numbers :class:`Complex` is a subclass of :class:`Number`. Complex numbers
can undergo the basic operations of addition, subtraction, can undergo the basic operations of addition, subtraction,
multiplication, division, and exponentiation, and you can retrieve the multiplication, division, and exponentiation, and you can retrieve the
