The math.sqrt() method returns the square root of a number. Note: The number must be greater than or equal to 0.

Jan 20, 2022 · The math module from the standard library has a sqrt function to calculate the square root of a number. It takes any type that can be converted to float (which includes int ) and returns a float .

2 days ago · math. isqrt (n) ¶ Return the integer square root of the nonnegative integer n. This is the floor of the exact square root of n, or equivalently the greatest integer a such that a² ≤ n. For some applications, it may be more convenient to have the least integer a such that n ≤ a², or in other words the ceiling of the exact square root of n.

The Python square root function, sqrt(), is part of the math module and is used to calculate the square root of a given number. To use it, you import the math module and call math.sqrt() with a non-negative number as an argument.

Feb 14, 2025 · math.sqrt() returns the square root of a number. It is an inbuilt function in the Python programming language, provided by the math module . In this article, we will learn about how to find the square root using this function.

Sep 4, 2021 · In this tutorial, you’ll learn how to calculate use Python to calculate the square root of a number, using the .sqrt() function. You’ll learn how to do this with, and without, the popular math library that comes built into Python.

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.
