5 Numeric and Mathematical Modules
6 ********************************
8 The modules described in this chapter provide numeric and math-related functions
9 and data types. The :mod:`numbers` module defines an abstract hierarchy of
10 numeric types. The :mod:`math` and :mod:`cmath` modules contain various
11 mathematical functions for floating-point and complex numbers. For users more
12 interested in decimal accuracy than in speed, the :mod:`decimal` module supports
13 exact representations of decimal numbers.
15 The following modules are documented in this chapter:
