how to find the square root of a negative number in python Numpy has an inbuilt cube root function cbrt that handles negative numbers fine import numpy as np np cbrt 8 2 0 This was added in version 1 10 0 released 2015 10 06 Also works for numpy array list inputs np cbrt 8 27 array 2 3
If you attempt to pass a negative number to sqrt then you ll get a ValueError because negative numbers are not in the domain of possible real squares Instead the square root of a negative number would need to be complex which is outside the scope of the Python square root function Square Roots in the Real World In this article we will cover how to compute the square root of negative inputs with emath in Python using NumPy Example Input 3 4 Output 0 1 73205081j 0 2 j Explanation Square root of a negative input NumPy emath sqrt method The np emath sqrt method from the NumPy library calculates the square root of complex inputs
