To return the result of the power to which the input value is raised with scimath, use the scimath.power() method in Python. Returns x to the power p, i.e. the result of x**p. If x and p are scalars, so is out, otherwise an array is returned.
If x contains negative values, the output is converted to the complex domain. The parameter x is the input value. The parameter p is the power(s) to which x is raised. If x contains multiple values, p has to either be a scalar, or contain the same number of values as x. In the latter case, the result is x[0]**p[0], x[1]**p[1], ....
Steps
At first, import the required libraries −
import numpy as np
Create a numpy array using the array() method. The array elements also includes negative values −
arr = np.array([2, -4, -8, 16, -32])
Display the array −
print("Our Array...\n",arr)Check the Dimensions −
print("\nDimensions of our Array...\n",arr.ndim)
Get the Datatype −
print("\nDatatype of our Array object...\n",arr.dtype)Get the Shape −
print("\nShape of our Array object...\n",arr.shape)
To return the result of the power to which the input value is raised with scimath, use the scimath.power() method −
print("\nResult...\n",np.emath.power(arr, 2))Example
import numpy as np
# Create a numpy array using the array() method
# The array elements also includes negative values
arr = np.array([2, -4, -8, 16, -32])
# Display the array
print("Our Array...\n",arr)
# Check the Dimensions
print("\nDimensions of our Array...\n",arr.ndim)
# Get the Datatype
print("\nDatatype of our Array object...\n",arr.dtype)
# Get the Shape
print("\nShape of our Array object...\n",arr.shape)
# To return the result of the power to which the input value is raised with scimath, use the scimath.power() method in Python
print("\nResult...\n",np.emath.power(arr, 2))Output
Our Array... [ 2 -4 -8 16 -32] Dimensions of our Array... 1 Datatype of our Array object... int64 Shape of our Array object... (5,) Result... [ 4.+0.j 16.-0.j 64.-0.j 256.+0.j 1024.-0.j]
