21 окт. 2014 г. · I'm trying to calculate the 8th root square of a value or its ^1/8, but numpy is always returning the wrong value.

20 февр. 2017 г. · Let's say I'm considering M=N**2 where N is an integer. It appears that numpy. sqrt(M) returns a float (actually numpy. float64).

3 окт. 2021 г. · Since typically the idenity xᵃ = exp(a⋅log(x)) is used to define the general power, you'll get the root corresponding to the chosen branch ...

23 мая 2018 г. · I want to calculate the n-th odd root of some numbers in python. Numpy as a cube root function. Using that function I can compute x^(1/3).

8 окт. 2013 г. · nth root of x is x^(1/n), so you can do 9**(1/2) to find the 2nd root of 9, for example. In general, you can compute the nth root of x as: x**(1/n).

15 мар. 2013 г. · I'm trying to write an algorithm croot(k, n), that returns the kth root of unity with n == n. I'm getting mostly the right answer, however it's giving me ...

11 июл. 2013 г. · I'm trying to make a simple code for power 12 to 4(12 ** 4). I have the output num (20736) but when I want to figure returns (20736) to its original value (12).

16 июн. 2015 г. · When I take an nth root in Python and NumPy, which of the n existing roots do I actually get? 0 · Exact value of a root on Python · 0 · Can ...

13 мар. 2013 г. · I want it to be exact (i.e. return an integer), and raise an exception if the input isn't a perfect square. I tried using this code: def isqrt(n): ...

21 июл. 2023 г. · I am scaling data using the built-in power operation in Python. However, I noticed that when trying to nth-root negative numbers (for odd n), I ...
