Hi everyone,
when I use np.exp(A) with the development version 2.0.23 where A is some matrix, the results are totally wrong.
Example:
import numpy as np
A = np.arange(9).reshape((3, 3))
print(np.exp(A))
array([[1.00000000e+00, 2.71828183e+00, 7.38905610e+00],
[2.00855369e+01, 5.45981500e+01, 1.48413159e+02],
[4.03428793e+02, 1.09663316e+03, 2.98095799e+03]])
import pnumpy as pn
print(np.exp(A))
array([[ 8.98846567e+307, inf, -2.05514945e-308],
[-5.58647539e-308, -1.51856145e-307, -4.12787801e-307],
[-1.12207358e-306, -3.05011222e-306, 2.98095799e+003]])
To me, it kind of looks like the first two entries are garbage, the last one is in this case correct (but it's not for arange(12) and reshape((4,3))), and the rest of the wrong entries should be divided by -2.78134232e-309 which is approximately e times 1e-309. I hope you can help me!
Thanks in advance!
