# Python math Functions

Python math Functions – This Python tutorial will explain the use of Python math functions in Python Programs with example Python scripts and their output.

### What is a Python math Module?

The Python programming language has a math module. The math module contains different functions for general math calculations.

### What are different math functions?

There many math functions present in math module. For example, the math module contains the following functions:
sqrt() function
factorial() function
pow() function
exp() function
log() function
log10() function
sin() function
cos() function
tan() function
floor() function
ceil() function etc.

### How we can use math module and its functions?

We must import the math module in our Python program. Then we can use math functions.

### What is Python import statement?

import statement is used to import standard modules of Python.

For example to import math module, we will write import statement as follows:

import math

### Use and Examples ofÂ  Math Functions

```# This Python program show the use of
# different math functions present in

import math

c = math.ceil(7.4)
print('ciel(7.4)=',c)

f = math.floor(7.4)
print('floor(7.4)=',f)

s = math.sqrt(25)
print('sqrt(25)=',s)

f = math.factorial(4)
print('factorial(4)=',f)

p = pow(2,3)
print('pow(2,3)=',p)

a = abs(-5.50)
print('abs(-5.50)=',a)

s = math.sin(0)
print('sin(0)=',s)

c = math.cos(0)
print('cos(0)=',c)

t = math.tan(0)
print('tan(0)=',t)
```
```The output will be:
ciel(7.4)= 8
floor(7.4)= 7
sqrt(25)= 5.0
factorial(4)= 24
pow(2,3)= 8
abs(-5.50)= 5.5
sin(0)= 0.0
cos(0)= 1.0
tan(0)= 0.0

```
