# numpy.floor_divide() in Python

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

 `# 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

 `# 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

 `# 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]```
