numpy.floor(x [,out])= ufunc'floor'):此數學函數返回數組元素的底數。標量x的底數是最大整數i,因此i
參數:
a:[array_like] Input arrayReturn : The floor of each element.
代碼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)
輸出:
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.]
代碼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)
輸出:
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.]
