|  | 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. The :mod:`decimal` | 
|  | module supports exact representations of decimal numbers, using arbitrary precision | 
|  | arithmetic. | 
|  |  | 
|  | The following modules are documented in this chapter: |
