numpy.around() in Python

Last Updated : 08 Mar, 2024

numpy.around(arr, decimals = 0, out = None) : This mathematical function helps user to evenly round array elements to the given number of decimals. 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

import numpy as np

in_array = [.5, 1.5, 2.5, 3.5, 4.5, 10.1]
print ("Input array : \n", in_array)

round_off_values = np.around(in_array)
print ("\nRounded values : \n", round_off_values)


in_array = [.53, 1.54, .71]
print ("\nInput array : \n", in_array)

round_off_values = np.around(in_array)
print ("\nRounded values : \n", round_off_values)

in_array = [.5538, 1.33354, .71445]
print ("\nInput array : \n", in_array)

round_off_values = np.around(in_array, decimals = 3)
print ("\nRounded values : \n", 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]

numpy.arange() in Python

numpy.arange() function creates an array of evenly spaced values within a given interval. It is similar to Python's built-in range() function but returns a NumPy array instead of a list. Let's understand with a simple example:Pythonimport numpy as np #create an array arr= np.arange(5 , 10) print(arr

numpy.find() in Python

numpy.core.defchararray.find(arr, substring, start=0, end=None): Finds the lowest index of the sub-string in the specified range. Parameters: arr : array-like or string to be searched. substring : substring to search for. start, end : [int, optional] Range to search in. Returns : An integer array wi

NumPy Array in Python

NumPy (Numerical Python) is a powerful library for numerical computations in Python. It is commonly referred to multidimensional container that holds the same data type. It is the core data structure of the NumPy library and is optimized for numerical and scientific computation in Python. Table of C

numpy.angle() in Python

numpy.angle() function is used when we want to compute the angle of the complex argument. A complex number is represented by â€œ x + yi " where x and y are real number and i= (-1)^1/2. The angle is calculated by the formula tan-1(x/y). Syntax : numpy.angle(z, deg=0) Parameters : z : [array_like] A com

numpy.fabs() in Python

numpy.fabs() function is used to compute the absolute values element-wise. This function returns the absolute values (positive magnitude) of the data in arr. It always return absolute values in floats. Syntax : numpy.fabs(arr, /, out=None, *, where=True, casting='same_kind', order='K', dtype=None, u

numpy.greater() in Python

The numpy.greater() checks whether x1 is greater than x2 or not. Syntax : numpy.greater(x1, x2[, out]) Parameters : x1, x2 : [array_like]Input arrays. If x1.shape != x2.shape, they must be broadcastable to a common shape out : [ndarray, boolean]Array of bools, or a single bool if x1 and x2 are scala

numpy.floor() in Python

The numpy.floor() function returns the largest integer less than or equal to each element in the input array. It effectively rounds numbers down to the nearest whole number. Let's understand with an example:Pythonimport numpy as np a = [0.5, 1.5, 2.5, 3, 4.5, 10.1] res = np.floor(a) print("Floored:"
