The :mod:`numbers` module defines an abstract hierarchy of 10numeric types. The :mod:`math` and :mod:`cmath` modules contain various 11mathematical functions for floating-point and complex numbers. The :mod:`decimal` 12module supports exact representations of decimal numbers, using arbitrary precision 13arithmetic. 14 15The following modules are documented in this chapter: 16 17 18.. toctree:: 19 20 numbers.rst 21 math.rst 22 cmath.rst 23 decimal.rst 24 fractions.rst 25 random.rst 26 statistics.rst 27
