# Python Math Inf

The Math module gives you access to the C standard’s mathematical functions. These routines do not handle complex numbers; instead, they use the cmath module’s functions with the same name. Because most users do not wish to study as much mathematics as is required to understand complex numbers, a distinction is made between functions that support complex numbers and those that do not. Receiving an exception rather than a complex result allows the programmer to discover the unexpected complex number supplied as a parameter earlier, allowing them to figure out how and why it was generated in the first place.

Now letâ€™s talk about the core idea of this article which is Math inf. Infinity is an ambiguous number that can be both positive and negative. A number represents infinity; the sum of two numeric values can occasionally result in a numeric pattern with a distinct pattern; it can be a negative or positive value. Its purpose is to compare the result of different algorithms and then choose the best one. In general, an initial value can be either positive or negative infinity; we must ensure that no input value is larger or smaller. A defined method or approach does not exist for expressing infinity as an integer in Python. This is similar to a core feature of several other widely used programming languages. Because Python is indeed a dynamically typed language, and for this reason, you can use the float keyword to show infinity as an integer. As a result, we can’t express infinity in Python, or we may say that there isn’t a way to show infinity as an integer. Float (inf) can perfectly be used as an integer. In Python, inf and -inf indicate positive and negative infinity, respectively. We’ll go through the subject in-depth and present examples in this article.

## Example 1:

Here’s a Python program for defining positive and negative infinity integers. Because it can be both positive and negative, infinity can be written as a float(‘inf’) or a float(‘-inf’). The code below shows how the stuff mentioned above is implemented. We defined a positive infinite integer and reported the result in the first line. Following that, we defined a negative infinite number and displayed the result in the same manner.

positive_inf= float('inf')
print('Here is Positive Infinity: ', positive_inf)
negative_inf = float('-inf')
print('Here is Negative Infinity: ', negative_inf)

The above-mentioned code’s generated output can be seen here.

## Example 2:

We’re going to use Python’s math module in this example. The Python math module is a useful tool for dealing with mathematical operations. It’s included in the standard Python distribution and has been since the beginning. The math module’s functions are mostly thin wrappers around the mathematical functions of the C platform. The math module is efficient and follows the C standard because its underlying functions are built-in CPython. You can utilize the Python math module to perform common and useful mathematical computations within your application. Infinite integers can also be represented using Python’s math package. The following piece of code in the image shows how to do this:

import math
positive_inf = math.inf
print('Here is Positive Infinity: ', positive_inf)
negative_inf = -math.inf
print('Here is Negative Infinity: ', negative_inf)

The following is the output of the supplied code.

## Example 3:

Infinite float values can also be represented using Python’s decimal module. The decimal module in Python contains a variety of functions for handling numeric data and performing different mathematical operations on it. Using the decimal module, we can handle decimal numbers in the program. The decimal module includes utilities for managing and overcoming decimal precision issues. Decimal(‘Infinity’) is used for positive infinite values, and Decimal(‘-Infinity’) is used for infinite negative values. The following code explains how it’s done:

from decimal import Decimal
positive_inf = Decimal('Infinity')
print('Here is Positive Infinity: ', positive_inf)
negative_inf = Decimal('-Infinity')
print('Here is Negative Infinity: ', negative_inf)

The output of the code given above is here.

## Example 4:

Numpy, a Python library, is used in this example. The Python NumPy module combines several functions to make it simple to execute various scientific and mathematical procedures. As a result, the NumPy module may be thought of as a tool that any programmer can use to accomplish all kinds of mathematical and sophisticated calculating jobs. Infinite values can also be represented using Python’s Numpy module. Positive infinite values are represented by np.inf, whereas negative infinite values are represented by -np.inf. The following code shows how to use the Numpy library to express an infinite value:

import numpy as np
positive_inf = np.inf
print('Here is Positive Infinity: ', positive_inf)
negative_inf = -np.inf
print('Here is Negative Infinity: ', negative_inf)

The code’s result is shown below.

## Conclusion:

Python Infinity is very much an undefined (negative or positive) value, with positive infinity being greater than any other value in a particular code and negative infinity being less. However, the concept of portraying the infinite as an integer is incompatible with infinity’s definition. So yet, no programming language has been able to represent infinity as an integer. Because of the fact that Python is a dynamic language, float numbers can be used to represent infinite numbers. To represent infinity, float(‘inf’) can be used as an integer. This article has looked at alternative approaches to represent infinity in Python. We’ve discussed Python math inf in detail. We’ve also gone over several examples to help you grasp the concept.
