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.
