 | 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: |
