There are three distinct numeric types: :dfn:`integers`, :dfn:`floating
point numbers`, and :dfn:`complex numbers`. In addition, Booleans are a
-subtype of integers. Integers have unlimited precision. Floating point
-numbers are implemented using :ctype:`double` in C---all bets on their
-precision are off unless you happen to know the machine you are working
-with. Complex numbers have a real and imaginary part, which are each
-implemented using :ctype:`double` in C. To extract these parts from a
-complex number *z*, use ``z.real`` and ``z.imag``. (The standard library
-includes additional numeric types, :mod:`fractions` that hold rationals,
-and :mod:`decimal` that hold floating-point numbers with user-definable
-precision.)
