7 sie 2017 · >>> np.power(0, 0) 1 >>> np.exp(0 * np.log(0)) nan Hence, the exp(log) trick only works on a subset of inputs, while power works on all (valid) inputs. In addition to this, power is guaranteed to give full precision according to the IEEE 754 standard , while exp(log) may suffer from rounding errors.
Examples. >>> import numpy as np. Cube each element in an array. >>> x1 = np.arange(6) >>> x1 [0, 1, 2, 3, 4, 5] >>> np.power(x1, 3) array([ 0, 1, 8, 27, 64, 125]) Raise the bases to different exponents.
