ฟังก์ชัน numpy.emath.power() คำนวณ x**p หาก x มีค่าลบ ผลลัพธ์จะเป็นชนิดเชิงซ้อน
ขั้นตอน
import numpy as np
arr = np.array([2, -4, -8, 16, -32])
print("Our Array...\n", arr)
print("\nDimensions of our Array...\n", arr.ndim)
print("\nDatatype of our Array object...\n", arr.dtype)
print("\nShape of our Array object...\n", arr.shape)
print("\nResult...\n", np.emath.power(arr, 2))
