Mar 13, 2013 · Newton's method works perfectly well on integers: x = n. y = (x + 1) // 2. while y < x: x = y. y = (x + n // x) // 2. return x. This returns the largest integer x for which x * x does not exceed n. If you want to check if the result is exactly the square root, simply perform the multiplication to check if n is a perfect square.

Jan 20, 2022 · It takes any type that can be converted to float (which includes int) and returns a float. The power operator (**) or the built-in pow () function can also be used to calculate a square root. Mathematically speaking, the square root of a equals a to the power of 1/2.

Feb 24, 2025 · Given an integer X, find its square root. If X is not a perfect square, then return floor (√x). For example, if X = 11, the output should be 3, as it is the largest integer less than or equal to the square root of 11. We can also find the floor of the square root using Python’s built-in exponentiation operator (**) and then integer conversion.

Apr 25, 2025 · math.isqrt () method in Python is used to get the integer square root of the given non-negative integer value n. This method returns the floor value of the exact square root of n or equivalently the greatest integer a such that a 2 <= n.

The math.sqrt() method returns the square root of a number. Note: The number must be greater than or equal to 0. Required. A number to find the square root of. If the number is less than 0, it returns a ValueError. If the value is not a number, it returns a TypeError. Math Methods. Track your progress - it's free!

Python’s sqrt() function calculates square roots using Python’s math.sqrt() for quick and accurate results in your programs. math.sqrt() calculates the square root of positive numbers and zero but raises an error for negative inputs.
