Python Math
Python has a built-in mathematical functions, including a comprehensive mathematical module, that allows you to perform numerical operations with numbers.
Built-in Math Functions
The min() and max() functions can be used to determine the lowest or highest value in iterable:
Example
x = min(5, 10, 25)
y = max(5, 10, 25)
print(x)
print(y)
The abs() function returns the total (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 (xy).
Example
x = pow(4, 3)
print(x)
The Math Module
Python also has a built-in module called math, which expands the list of mathematical functions.
To use it, you must enter a math module:
import math
Once you have entered the math module, you can start using module methods and constants.
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 rotates the number upwards to the nearest number, and the math.floor() method rotates the number downwards to the nearest number, and returns the result:
Example
import
math
x = math.ceil(1.4)
y = math.floor(1.4)
print(x) #
returns 2
print(y) # returns 1
math.pi constant, returns the PI value (3.14 ...):
Example
import
math
x = math.pi
print(x)
