numpy.floor() in Python
  • Last Updated : 04 Dec, 2020

The numpy.floor) is a mathematical function that returns the floor of the elements of array. The floor of the scalar x is the largest integer i, such that i <= x.

Syntax : numpy.floor(x[, out]) = ufunc ‘floor’)
Parameters :
a : [array_like] Input array

Return : The floor of each element.

 
Code #1 : Working




# Python program explaining
# floor() function
  
import numpy as np
  
in_array = [.5, 1.5, 2.5, 3.5, 4.5, 10.1]
print ("Input array : \n", in_array)
  
flooroff_values = np.floor(in_array)
print ("\nRounded values : \n", flooroff_values)
  
  
in_array = [.53, 1.54, .71]
print ("\nInput array : \n", in_array)
  
flooroff_values = np.floor(in_array)
print ("\nRounded values : \n", flooroff_values)
  
in_array = [.5538, 1.33354, .71445]
print ("\nInput array : \n", in_array)
  
flooroff_values = np.floor(in_array)
print ("\nRounded values : \n", flooroff_values)

Output :



Input array : 
 [0.5, 1.5, 2.5, 3.5, 4.5, 10.1]

Rounded values : 
 [  0.   1.   2.   3.   4.  10.]

Input array : 
 [0.53, 1.54, 0.71]

Rounded values : 
 [ 0.  1.  0.]

Input array : 
 [0.5538, 1.33354, 0.71445]

Rounded values : 
 [ 0.  1.  0.]

 

Code #2 : Working




# Python program explaining
# floor() function
import numpy as np
  
in_array = [1.67, 4.5, 7, 9, 12]
print ("Input array : \n", in_array)
  
flooroff_values = np.floor(in_array)
print ("\nRounded values : \n", flooroff_values)
  
  
in_array = [133.000, 344.54, 437.56, 44.9, 1.2]
print ("\nInput array : \n", in_array)
  
flooroff_values = np.floor(in_array)
print ("\nRounded values upto 2: \n", flooroff_values)

Output :

Input array : 
 [1.67, 4.5, 7, 9, 12]

Rounded values : 
 [  1.   4.   7.   9.  12.]

Input array : 
 [133.0, 344.54, 437.56, 44.9, 1.2]

Rounded values upto 2: 
 [ 133.  344.  437.   44.    1.]
