Syntax
The syntax to call isqrt() function is
math.isqrt(x)
where
Parameter | Required | Description |
---|---|---|
x | Yes | A non-negative integer. |
Examples
1. Find the square root of an integer value
In the following program, we find the square root of an integer value 11.
Output
isqrt(x) : 3
2. Find the square root of a float value
Since isqrt() accepts only integer value, if float value is passed as argument to it, the function raises TypeError.
Python Program
import math
x = 11.5
result = math.isqrt(x)
print('isqrt(x) :', result)
Run Code CopyOutput
TypeError: 'float' object cannot be interpreted as an integer
