# How to calculate the element-wise absolute value of NumPy array?

• Last Updated : 29 Aug, 2020

Let’s see the program for finding the element-wise absolute value of NumPy array. For doing this task we are using numpy.absolute() function of NumPy library. This mathematical function helps to calculate the absolute value of each element in the array.

Syntax: numpy.absolute(arr, out = None, ufunc ‘absolute’)

Return: An array with absolute value of each element.

Let’s see an example:

Example 1: Element-wise absolute value of 1d-array.

## Python3

 `# import library``import` `numpy as np`` ` `# create a numpy 1d-array``array ``=` `np.array([``1``, ``-``2``, ``3``])`` ` `print``(``"Given array:\n"``, array)`` ` `# find element-wise``# absolute value``rslt ``=` `np.absolute(array)`` ` `print``(``"Absolute array:\n"``, rslt)`

Output:

```Given array:
[ 1 -2  3]
Absolute array:
[1 2 3]
```

Example 2: Element-wise absolute value of 2d-array.

## Python3

 `# import library``import` `numpy as np`` ` `# create a numpy 2d-array``array ``=` `np.array([[``1``, ``-``2``, ``3``],``                  ``[``-``4``, ``5``, ``-``6``]])`` ` `print``(``"Given array:\n"``,``      ``array)`` ` `# find element-wise``# absolute value``rslt ``=` `np.absolute(array)`` ` `print``(``"Absolute array:\n"``,``      ``rslt)`

Output:

```Given array:
[[ 1 -2  3]
[-4  5 -6]]
Absolute array:
[[1 2 3]
[4 5 6]]
```

Example 3: Element-wise absolute value of 3d-array.

## Python3

 `# import library``import` `numpy as np`` ` `# create a numpy 3d-array``array ``=` `np.array([``    ``[[``1``, ``-``2``, ``3``],``     ``[``-``4``, ``5``, ``-``6``]],``                  ` `    ``[[``-``7.5``, ``-``8.22``, ``9.0``],``     ``[``10.0``, ``11.5``, ``-``12.5``]]``                 ``])`` ` `print``(``"Given array:\n"``,``      ``array)`` ` `# find element-wise``# absolute value ``rslt ``=` `np.absolute(array)`` ` `print``(``"Absolute array:\n"``,``      ``rslt)`

Output:

```Given array:
[[[  1.    -2.     3.  ]
[ -4.     5.    -6.  ]]

[[ -7.5   -8.22   9.  ]
[ 10.    11.5  -12.5 ]]]
Absolute array:
[[[ 1.    2.    3.  ]
[ 4.    5.    6.  ]]

[[ 7.5   8.22  9.  ]
[10.   11.5  12.5 ]]]
```
