|

Parameters :

array: [array_like] Input array.
decimal: [int, optional] Decimal places we want to round off.

Default = 0. In case of -ve decimal, it specifies the n0. of positions to the left of the decimal point.

out: [optional] Output resulted array

Return:

 An array with all array elements being rounded off, having same type as input. 

Code # 1: Work

# Python program explaining
# round_ () function

import numpy as np

 

in_array = [. 5 , 1.5 , 2.5 , 3.5 , 4.5 , 10.1 ]

print ( " Input array: " , in_array) 

 

round_off_values ​​ = np.round_ (in_array)

print ( " Rounded values: " , round_off_values)

 

 

in_array = [. 53 , 1.54 ,. 71 ]

print ( "Input array : " , in_array)

  

round_off_values ​​ = np.round_ (in_array)

print ( " Rounded values: " , round_off_values)

 

in_array = [. 5538 , 1.33354 ,. 71445 ]

print ( "Input array:" , in_array)

 

round_off_values ​​ = np.round_ (in_array, decimals = 3 )

print ( "Rounded values:" , round_off_values)

Output:

 Input array: [0.5, 1.5, 2.5, 3.5, 4.5, 10.1] Rounded values: [0. 2. 2. 4. 4. 10.] Input array: [0.53, 1.54, 0.71] Rounded values: [1. 2. 1.] Input array: [0.5538, 1.33354, 0.71445] Rounded values: [0.554 1.334 0.714] 

Code # 2: Work

# Python program explaining
# round_ () function

import numpy as np

 

in_array = [ 1 , 4 , 7 , 9 , 12 ]

print ( " Input array: " , in_array)

  

round_off_values ​​ = np.round_ (in_array)

print ( "Rounded values:" , round_off_values)

 

 

in_array = [ 133 , 344 , 437 , 449 , 12 ]

print ( "Input array:" , in_array)

 

round_off_values ​​ = np.round_ (in_array, decimals = - 2 )

print ( "Rounded values ​​upto 2:" , round_off_values)

  

in_array = [ 133 , 344 , 437 , 449 , 12 ]

print ( " Input array: " , in_array)

 

round_off_values ​​ = np.round_ (in_array, decimals = - 3 )

print ( "Rounded values ​​upto 3:" , round_off_values)

Exit :

 Input array: [1, 4, 7, 9, 12] Rounded values: [1 4 7 9 12] Input array: [133, 344, 437, 449, 12] Rounded values ​​upto 2: [100 300 400 400 0] Input array: [133, 344, 437, 449, 12] Rounded values ​​upto 3: [0 0 0 0 0]
