Michael Zippo 18.07.2021

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

   
  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

   round_off_values   =   np.around (in_array, decimals   =   -   2  ) 
   print   (  "Rounded values upto 2:"  , round_off_values) 
   
   in_array   =   [  133  ,   344  ,   437  ,   449  ,   12  ]

   round_off_values   =   np.around (in_array, decimals   =   -   3  )  
   print   (  "Rounded values upto 3:"  , round_off_values)

Output:

 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]
