Jan 18, 2015 · def cube(x): if 0<=x: return x**(1./3.) return -(-x)**(1./3.) print (cube(8)) print (cube(-8)) Here is the full answer for both negative and positive numbers. >>> 2.0 -2.0 >>> Or here is a one-liner; root_cube = lambda x: x**(1./3.) if 0<=x else -(-x)**(1./3.)

In Python, you may find floating cube root by: >>> def get_cube_root(num): ... return num ** (1. / 3) ... >>> get_cube_root(27) 3.0 In case you want more generic approach to find nth root, you may use below code which is based on Newton's method:

Jul 27, 2023 · Given a number n, find the cube root of n. We can use binary search. First we define error e. Let us say 0.0000001 in our case. The main steps of our algorithm for calculating the cubic root of a number n are: Check if the absolute value of (n – mid*mid*mid) < e. If this condition holds true then mid is our answer so return mid.

Mar 21, 2018 · x**(1/3) won't return the real root for negative numbers, so use math.cbrt in python 3.11+ or a quick workaround: from math import copysign def real_cbrt(x): return copysign(abs(x)**(1/3), x)

Feb 27, 2024 · cube_root = lambda x: x ** (1/3) print('The cube root of 125 is', cube_root(125)) Output: The cube root of 125 is 5.0. This snippet demonstrates a lambda function that computes the cube root. It’s a compact solution that showcases the flexibility of Python for small, inline calculations. Summary/Discussion. Method 1: Using the ** operator ...

Feb 11, 2024 · In this tutorial, we are going to learn how to find the cube root of a number in Python. How to find the cube root of a number in Python. Update: Some of our viewers reported the code was not working properly so I have added a new updated code here in the first place: x = 8 cube_root = x ** (1/3) print(cube_root) Output: 2.0

Feb 2, 2024 · One straightforward approach to calculate the cube root of an integer or a float variable in Python is by using the exponent symbol **. The exponent symbol ** is an operator that raises a number to a specified power. To compute the cube root, we can leverage this symbol by setting the power to 1/3. The syntax is as follows:

Feb 3, 2025 · Python provides powerful functions for working with square roots and cube roots. The math module contains the sqrt() function for square root calculations and cbrt() function for cube root calculations.

Mar 9, 2024 · To find cube roots, we can solve the equation \( x^3 – a = 0 \) where \( a \) is the number we want to find the cube root of. This can be done using the root-finding algorithms in scipy.linalg . Here’s an example:
