Math In Python
We are exploring Python math. Throughout this article, we have provided examples to satisfy the desire for knowledge of our readers.
In Python math, you can perform mathematical operations on numbers with Python’s built-in math functions, along with an extensive math module.
Python Math Module
Mathematical calculations are sometimes necessary when working on financial and scientific projects. Such calculations can be handled by Python math module.
Python math module provides functions to perform both basic operations (such as addition, subtraction, multiplication, and division) and advanced ones such as trigonometric, logarithms, and exponentials.
In addition, Python comes with a built-in module known as Python math, which increases the list of mathematical functions.
You have to import the math module to utilize it:
Example
After importing the math module, you can utilize its methods and constants.
The math.sqrt() method, for instance, provides the square root of a number as follows:
Example:
Example:
Math.ceil() rounds a number up to its closest integer, and math.floor() rounds a number down to its closest integer, and prints the outcome as follows:
Example:
math.pi constant displays the value of PI (3.14…) as follows:
Example:
Python Math Built-in Functions
To obtain the smallest or greatest value in an iterable, call the min() and max() functions:
Example:
Another Example:
According to Python math, we can utilize the abs() function to provide a number’s absolute value (positive value):
Example:
Another Example:
By calling a function such as pow(x, y), the user gets the value of x to the power of y (x^y).
Give the power of 2 of 7 (the identical number as 7 * 7):
Example:

Python Math Uses
Here are some common uses of the math module in Python:
- Computing square roots: Use the
math.sqrt()function to calculate the square root of a number. - Rounding numbers: The
math.ceil()function rounds a number up to the nearest integer, whilemath.floor()rounds it down. - Trigonometric functions: The
math.sin(),math.cos(), andmath.tan()functions compute the sine, cosine, and tangent of an angle, respectively. - Exponential and logarithmic functions: Use
math.exp()to compute the exponential function e^x,math.log()to calculate the natural logarithm, andmath.log10()for the base-10 logarithm. - Constants: The
math.piconstant represents the value of π (pi), andmath.erepresents Euler’s number (e). - Converting between degrees and radians: The
math.radians()function converts an angle from degrees to radians, andmath.degrees()converts from radians to degrees. - Power and absolute value: The
