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:
