Numeric and Mathematical Modules
********************************

The modules described in this chapter provide numeric and math-related functions
and data types. The :mod:`math` and :mod:`cmath` 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:
