WHAT IS MATH MODULE FUNCTIONS AND HOW TO USE IN PYTHON PROGRAMMING

MATH MODULE FUNCTIONS

The math module defines functions for performing various common mathematical calculations. Recall from the previous chapter that an import statement of the following form enables you to use a module’s definitions via the module’s name and a dot (.):

In [1]: import math

For example, the following snippet calculates the square root of 900 by calling the math module’s sqrt function, which returns its result as a float value:

In [2]: math.sqrt(900)
Out[2]: 30.0

Similarly, the following snippet calculates the absolute value of ­10 by calling the math module’s fabs function, which returns its result as a float value:

In [3]: math.fabs(­-10)
Out[3]: 10.0

Some math module functions are summarized below—you can view the complete list at
