# Python Math

Python features a number of built-in `math` functions, including a large math module, which enables mathematical tasks to be carried out on numbers.

## Built-in Math Functions

Example 1 :- The functions `min()` and `max()` are used to find in an iterable the lowest or highest value :

``````x = min(5, 10, 25)
y = max(5, 10, 25)

print(x)
print(y)``````

Output :-

5
25

Example 2 :- The function `abs()` returns the absolute value (positive) of the provided number. It removes signs (positive (+) sign or negative (-) sign) from the given number.

``````x = abs(-7.25)

print(x)``````

Output :-

7.25

The function `pow(x,y)` returns the value x to the power y (xy) :

Example 3 :- Return the value of 4 to the power of 3 (same as 4 * 4 * 4):

``````x = pow(4, 3)

print(x)``````

Output :-

64

## The Math Module

Python additionally has an integrated `math` module which extends the mathematical list functions.

The `math` module has to be imported to use it :

``import math``

You can start with the methods and constants of the module when you have imported the `math` module.

Example 1 :- For example `math.sqrt()` returns a number's square root :

``````import math

x = math.sqrt(64)

print(x)``````

Output :-

8.0

Example 2 :- The function `math.ceil()` rounds a number up to its nearest integer, and the method `math.floor()` rounds down to its closest integer and returns the result :

``````#Import math library
import math

#Round a number upward to its nearest integer
x = math.ceil(1.4)

#Round a number downward to its nearest integer
y = math.floor(1.4)

print(x)
print(y)``````

Output :-

2
1

Example 3 :- The `math.pi` constant, PI value yields (3.14...) :

``````import math

x = math.pi

print(x)``````

Output :-

3.141592653589793
