It includes built-in types for managing integer and floating-point numbers, which are suitable for the basic math that might appear in an average application. The standard library includes modules for more advanced needs.
Python’s built-in floating-point numbers use the underlying double representation. They are sufficiently precise for most programs with mathematical requirements, but when more accurate representations of non-integer values are needed, the decimal (page 239) and fractions (page 250) modules will be useful. Arithmetic with decimal and fractional values retains precision, but is not as fast as the native ...
