Python3.x Python3 sqrt() Function

Python3 Numbers

---

Description

The sqrt() method returns the square root of the number x.

---

Syntax

Here is the syntax for the sqrt() method:

import math
math.sqrt( x )

Note: sqrt() cannot be accessed directly; you need to import the math module and call the method via a static object.

---

Parameters

• x -- A numeric expression.

---

Return Value

Returns the square root of the number x.

---

Example

The following example demonstrates the use of the sqrt() method:

Example

#!/usr/bin/python3
import math  # Import the math module
print("math.sqrt(100) : ", math.sqrt(100))
print("math.sqrt(7) : ", math.sqrt(7))
print("math.sqrt(math.pi) : ", math.sqrt(math.pi))

After running the above example, the output is:

math.sqrt(100) : 10.0
math.sqrt(7) : 2.6457513110645907
math.sqrt(math.pi) : 1.7724538509055159
