 Numeric and Mathematical Modules
 ********************************
 
 The modules described in this chapter provide numeric and math-related functions
-and data types. The :mod:`math` and :mod:`cmath` contain  various mathematical
-functions for floating-point and complex numbers. For users more interested in
-decimal accuracy than in speed, the  :mod:`decimal` module supports exact
-representations of  decimal numbers.
+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. For users more
+interested in decimal accuracy than in speed, the :mod:`decimal` module supports
+exact representations of decimal numbers.
 
 The following modules are documented in this chapter:
