6. Numeric and Mathematical Modules

The modules described in this chapter provide numeric and math-related functions and data types. The math and cmath contain various mathematical functions for floating-point and complex numbers. For users more interested in decimal accuracy than in speed, the decimal module supports exact representations of decimal numbers.

The following modules are documented in this chapter:

`math`		Mathematical functions (`sin()` etc.).
`cmath`		Mathematical functions for complex numbers.
`decimal`		Implementation of the General Decimal Arithmetic Specification.
`random`		Generate pseudo-random numbers with various common distributions.
`itertools`		Functions creating iterators for efficient looping.
`functools`		Higher-order functions and operations on callable objects.
`operator`		All Python's standard operators as built-in functions.
