numpy.right_shift

numpy.right_shift(x1, x2[, out])

Shift the bits of an integer to the right.

Bits are shifted to the right by removing x2 bits at the right of x1. Since the internal representation of numbers is in binary format, this operation is equivalent to dividing x1 by 2**x2.

Parameters:

x1 : array_like, int

Input values.

x2 : array_like, int

Number of bits to remove at the right of x1.

Returns:

out : ndarray, int

Return x1 with bits shifted x2 times to the right.

left_shift

Shift the bits of an integer to the left.

binary_repr

Return the binary representation of the input number as a string.

Examples

>>> np.binary_repr(10)
'1010'
>>> np.right_shift(10, 1)
5
>>> np.binary_repr(5)
'101'

>>> np.right_shift(10, [1,2,3])
array([5, 2, 1])
