Shift Bits of Integer to the Right in NumPy

To shift the bits of an integer to the right, use the numpy.right_shift() method in Python Numpy. We have set the count of shifts as a new array. Bits are shifted to the right x2. Because the internal representation of numbers is in binary format, this operation is equivalent to dividing x1 by 2**x2.

The x1 is the Input values. The x2 is the number of bits to remove at the right of x1. If x1.shape != x2.shape, they must be broadcastable to a common shape.

The function right_shift() returns x1 with bits shifted x2 times to the right. This is a scalar if both x1 and x2 are scalars.

Steps

At first, import the required library −

import numpy as np

Create a One-Dimensional array. The datatype is set using the "dtype" parameter. We have set the datatype to signed integer type −

arrRight = np.array([2, 3, 5],dtype=np.int8)

Displaying our array −

print("Array...
",arr)

Get the datatype −

print("
Array datatype...
",arr.dtype)

Get the dimensions of the Array −

print("
Array Dimensions...
",arr.ndim)

Get the shape of the Array −

print("
Our Array Shape...
",arr.shape)

Get the number of elements of the Array −

print("
Elements in the Array...
",arr.size)

The actual integer value −

val = 25

To shift the bits of an integer to the right, use the numpy.right_shift() method. We have set the count of shifts as an array arrRight −

print("
Result (right shift)...
",np.right_shift(val, arrRight))

Example

import numpy as np

# Create a One-Dimensional array
# The datatype is set using the "dtype" parameter
# We have set the datatype to signed integer type

arrRight = np.array([2, 3, 5],dtype=np.int8)
# Displaying our array
print("Array...
",arrRight)

# Get the datatype
print("
Array datatype...
",arrRight.dtype)

# Get the dimensions of the Array
print("
Array Dimensions...
",arrRight.ndim)

# Get the shape of the Array
print("
Our Array Shape...
",arrRight.shape)

# Get the number of elements of the Array
print("
Elements in the Array...
",arrRight.size)

# The actual integer value
val = 25

# To shift the bits of an integer to the right, use the numpy.right_shift() method in Python Numpy
# We have set the count of shifts as an array arrRight
print("
Result (right shift)...
",np.right_shift(val, arrRight))

Output

Array...
[2 3 5]

Array datatype...
int8

Array Dimensions...
1

Our Array Shape...
(3,)

Elements in the Array...
3

Result (right shift)...
[6 3 0]
