## Python Math Sqrt

Python is a high-level, executable, and general-purpose programming language that can be utilized for various applications. It is frequently utilized in ML/machine learning, data science, AI, and web development. One of the most commonly used mathematical functions in Python is the “**sqrt()**” method that can be utilized to compute the square root while dealing with mathematical computations.

This article will explore the Python “**math.sqrt()**” method in detail, covering its syntax, parameter values, return values, and exceptions, along with examples.

## What is the “math.sqrt()” Method in Python?

The “**math.sqrt()**” method is a built-in functionality in the “**math**” module of Python, which is utilized to calculate the square root of a given number. It takes/accepts a single argument, which is a number, and returns its square root.

**Syntax of “math.sqrt()”**

math.sqrt(x)

In the above syntax, the “**math**” module is imported, and the “**math.sqrt()**” method is used to calculate the square root of the number “**x**”.

**Parameter Values of “math.sqrt()”**

The “math.sqrt()” method takes only one argument: a number. The particular number can be an “**Int/Integer**” or a “**Float**”. If the number is negative, the “math.sqrt()” method will return a complex number, which contains the absolute value of the square root.

**Return Values of “math.sqrt()”**

This method retrieves the input number’s square root. If the number is a positive integer or floating-point, the method will return a floating-point number. If the number is a negative integer or floating-point, the method will return a complex number instead.

## Examples of “math.sqrt()” in Python

Let’s look at the following examples of using the “math.sqrt()” method in Python:

**Example 1: Determining the Square Root of a Positive Number**

The below code is used to determine the square root value of the given number:

x = 16

print(math.sqrt(x))

In the above code, the “math” module is imported, and a variable “x” with the value of “16” is defined, respectively. After that, the “**math.sqrt()**” method is called on “x” to return the square root accordingly.

**Output**

The snippet above displays the square root of the defined integer appropriately.

**Example 2: Determining the Square Root of the Negative Number**

The “math.sqrt()” method raises a “**ValueError**” exception if the passed argument value is negative. Here is an example:

x = -16

print(math.sqrt(x))

In this code block, the “**negative number**” is passed as an argument to the “**math.sqrt()**” method to compute the square root accordingly.

**Output**

Based on the above snippet, the discussed exception is encountered.

## Conclusion

The “**sqrt()**” method of the “math” module in Python can be used to calculate the square root of a given number. This module also contains many other useful mathematical functions. The “math.sqrt()” method was discussed in this article along with its syntax, parameter values, return values, and exceptions.
