# numpy.floor_divide() in Python

• Difficulty Level : Medium
• Last Updated : 29 Nov, 2018

numpy.floor_divide(arr1, arr2, /, out = None, where = True, casting = ‘same_kind‘, order = ‘K‘, dtype = None) :

Array element from first array is divided by the elements from second array(all happens element-wise). Both arr1 and arr2 must have same shape.
It is equivalent to the Python // operator and pairs with the Python % (remainder), function so that b = a % b + b * (a // b) up to roundoff.

Parameters :

```arr1     : [array_like]Input array or object which works as numerator.

arr2     : [array_like]Input array or object which works as denominator.

out      : [ndarray, None, optional]Output array with same dimensions as
Input array, placed with result.

**kwargs : Allows you to pass keyword variable length of argument to a function.
It is used when we want to handle named argument in a function.

where    : [array_like, optional]True value means to calculate the universal
functions(ufunc) at that position, False value means to leave the
value in the output alone.
```

Return :

```An array with floor(x1 / x2)
```

Code 1 : arr1 divided by arr2

 `# Python program explaining ` `# floor_divide() function ` `import` `numpy as np ` ` `  `# input_array ` `arr1 ``=` `[``2``, ``2``, ``2``, ``2``, ``2``] ` `arr2 ``=` `[``2``, ``3``, ``4``, ``5``, ``6``] ` `print` `(``"arr1         : "``, arr1) ` `print` `(``"arr1         : "``, arr2) ` ` `  `# output_array ` `out ``=` `np.floor_divide(arr1, arr2) ` `print` `(``"\nOutput array : "``, out) `

Output :

```arr1         :  [2, 2, 2, 2, 2]
arr1         :  [2, 3, 4, 5, 6]

Output array :  [1 0 0 0 0]
```

Code 2 : elements of arr1 divided by divisor

 `# Python program explaining ` `# floor_divide() function ` `import` `numpy as np ` ` `  `# input_array ` `arr1 ``=` `[``2``, ``7``, ``3``, ``11``, ``4``] ` `divisor ``=` `3` `print` `(``"arr1         : "``, arr1) ` ` `  `# output_array ` `out ``=` `np.floor_divide(arr1, divisor) ` `print` `(``"\nOutput array : "``, out) `

Output :

```arr1         :  [2, 7, 3, 11, 4]

Output array :  [0 2 1 3 1]```

Code 3 : floor_divide handling results if arr2 has -ve elements

 `# Python program explaining ` `# floor_divide() function ` `import` `numpy as np ` ` `  `# input_array ` `arr1 ``=` `[``2``, ``6``, ``21``, ``21``, ``12``] ` `arr2 ``=` `[``2``, ``3``, ``4``, ``-``3``, ``6``] ` `print` `(``"arr1         : "``, arr1) ` `print` `(``"arr2         : "``, arr2) ` ` `  `# output_array ` `out ``=` `np.floor_divide(arr1, arr2) ` `print` `(``"\nOutput array : "``, out) `

Output :

```arr1         :  [2, 6, 21, 21, 12]
arr2         :  [2, 3, 4, -3, 6]

Output array :  [ 1  2  5 -7  2]```
