Python has a set of built-in math functions, including an extensive math module, that allows you to perform mathematical tasks on numbers.
Built-in Math Functions
The min() and max() functions can be used to find the lowest or highest value in an iterable:
Example
x = min(5, 10, 25)
y = max(5, 10, 25)
print(x)
print(y)The abs() function returns the absolute (positive) value of the specified number:
Example
x = abs(-7.25)
print(x)The pow( x , y ) function returns the value of x to the power of y (x y ).
Example
x = pow(4, 3)
print(x)The Math Module
Python has also a built-in module called math , which extends the list of mathematical functions.
To use it, you must import the math module:
import mathWhen you have imported the math module, you can start using methods and constants of the module.
The math.sqrt() method for example, returns the square root of a number:
Example
import
math
x = math.sqrt(64)
print(x)The math.ceil() method rounds a number upwards to its nearest integer, and the math.floor() method rounds a number downwards to its nearest integer, and returns the result:
Example
import
math
x = math.ceil(1.4)
y = math.floor(1.4)
print(x) #
returns 2
print(y) # returns 1The math.pi constant, returns the value of PI (3.14...):
Example
import
math
x = math.pi
print(x)
