.. _numeric: ******************************** 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: .. toctree:: numbers.rst math.rst cmath.rst decimal.rst fractions.rst random.rst statistics.rst
