The math module
This module implements a number of mathematical operations for floating point numbers. The functions are generally thin wrappers around the platform C library functions of the same name, so results may vary slightly across platforms in normal cases, or vary a lot in exceptional cases.
The cmath module provides similar functionality for complex numbers.
Example: Using the math module
# File: math-example-1.py import math print "e", "=>", math.e print "pi", "=>", math.pi print "hypot", "=>", math.hypot(3.0, 4.0) # and many others...
$ python math-example-1.py e => 2.71828182846 pi => 3.14159265359 hypot => 5.0
