Python Math Functions and Math Module

Python provides several built-in mathematical functions for basic calculations. For advanced mathematical operations, Python also includes a powerful math module.

Built-in Math Functions

Finding Minimum and Maximum Values

The min() and max() functions help you quickly determine the smallest and largest values from a collection of numbers.

numbers = [12, 45, 7, 89, 23] lowest = min(numbers) highest = max(numbers) print("Minimum value:", lowest) print("Maximum value:", highest)

Minimum value: 7 Maximum value: 89

Absolute Value

The abs() function converts a negative number into its positive form, while positive numbers remain unchanged.

value = -15.8 result = abs(value) print("Absolute value:", result)

Absolute value: 15.8

Power Function

The pow() function raises a number to a specified power.

result = pow(3, 4) print("Power result:", result)

Power result: 81

Python Math Module

For more complex mathematical calculations, Python provides the math module. To access its features, you must import it first.

import math

Square Root Calculation

The math.sqrt() function returns the square root of a number.

import math number = 81 root = math.sqrt(number) print("Square root:", root)

Square root: 9.0

Rounding Numbers

• math.ceil() rounds a number up to the nearest integer.
• math.floor() rounds a number down to the nearest integer.

import math value = 6.7 rounded_up = math.ceil(value) rounded_down = math.floor(value) print("Ceil value:", rounded_up) print("Floor value:", rounded_down)

Ceil value: 7 Floor value: 6

Mathematical Constant π (Pi)

The math.pi constant provides an accurate value of π (pi), commonly used in geometry and trigonometry.

import math radius = 5 area = math.pi * radius * radius print("Area of circle:", area)

Area of circle: 78.53981633974483
