Python numpy.square() function returns a new array with the element value as the square of the source array elements. The source array remains unchanged.

## Python numpy.square() Examples

It’s a utility function to quickly get the square of the matrix elements. Let’s look at the examples of numpy square() function with integer, float, and complex type array elements.

### 1. numpy square() int array

``````import numpy as np

# ints
array_2d = np.array([[1, 2, 3], [4, 5, 6]])

print(f'Source Array:\n{array_2d}')

array_2d_square = np.square(array_2d)

print(f'Squared Array:\n{array_2d_square}')
``````

Output:

``````Source Array:
[[1 2 3]
[4 5 6]]
Squared Array:
[[ 1  4  9]
[16 25 36]]
``````

### 2. numpy square() floating point array

``````import numpy as np

array_2d_float = np.array([1.2, 2.3, 5])

print(f'Source Array:\n{array_2d_float}')

array_2d_float_square = np.square(array_2d_float)

print(f'Squared Array:\n{array_2d_float_square}')
``````

Output:

``````Source Array:
[1.2 2.3 5. ]
Squared Array:
[ 1.44  5.29 25.  ]
``````

Notice that the integer in the floating-point array has been converted to a floating-point number.

### 3. numpy square() complex numbers array

``````arr = np.array([1 + 2j, 2 + 3j, 4])

print(f'Source Array:\n{arr}')

arr_square = np.square(arr)

print(f'Squared Array:\n{arr_square}')
``````

Output:

``````Source Array:
[1.+2.j 2.+3.j 4.+0.j]
Squared Array:
[-3. +4.j -5.+12.j 16. +0.j]
``````

Here the integer element is converted to a complex number. Reference: API Doc
