Python numpy.floor()用法及代码示例


numpy.floor(x [,out])= ufunc'floor'):此数学函数返回数组元素的底数。标量x的底数是最大整数i,因此i

参数:
a:[array_like] Input array

Return : The floor of each element.




代码1:工作

# 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)

输出:

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.]

代码2:工作

# 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)

输出:

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.]
