The :mod:`numbers` module defines an abstract hierarchy of 10 numeric types. The :mod:`math` and :mod:`cmath` modules contain various 11 mathematical functions for floating-point and complex numbers. For users more 12 interested in decimal accuracy than in speed, the :mod:`decimal` module supports 13 exact representations of decimal numbers. 14 15 The 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 itertools.rst 27 functools.rst 28 operator.rst 29
