Numeric and Mathematical Modules
********************************
The modules described in this chapter provide numeric and math-related functions
and data types. The :mod:`numbers` module defines an abstract hierarchy of
numeric types. The :mod:`math` and :mod:`cmath` modules contain various
mathematical functions for floating-point and complex numbers. For users more
interested in decimal accuracy than in speed, the :mod:`decimal` module supports
exact representations of decimal numbers.
The following modules are documented in this chapter:
