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 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]
