The **`math` module** is a built-in Python library. It helps in numerous *mathematical* functions following the C standard.

This works for *real* numbers only.

# Basic functions

| Functions    |  Description   |
| --- | --- |
|**math.ceil( value )**| It returns the smallest integer greater than or equal to *value*.|
|**math.copysign( value1,value2 )**   |It returns the float with magnitude of *value1* and sign of *value2*.|
|**math.fabs( value )**|It returns the absolute of *value*.     |
|**math.factorial( value )**| It returns the factorial of *value*.   |
|**math.floor( value )**| It returns the largest integer greater than or equal to *value*.   |
|**math.fsum( iterable )**| It returns the float sum of the values of the iterable.    |

# Importing Math library.
import math

#ceiling function
print(math.ceil(10.555))

#factorial function
print(math.factorial(3))


There are numerous other [functions](https://docs.python.org/3/library/math.html) as well:
* **Logarithmic function:** Returns the natural logarithm of a specified number.
* **Exponential function:** Returns a float number after raising **e** to a specified number.
* **Square root function:** Returns the square root of a specified number.
