numpy.right_shift
-
numpy.right_shift(x1, x2, /, out=None, *, where=True, casting='same_kind', order='K', dtype=None, subok=True[, signature, extobj]) = <ufunc 'right_shift'>
-
Shift the bits of an integer to the right.
Bits are shifted to the right
x2
. Because the internal representation of numbers is in binary format, this operation is equivalent to dividingx1
by2**x2
.Parameters: x1 : array_like, int
Input values.
x2 : array_like, int
Number of bits to remove at the right of
x1
.out : ndarray, None, or tuple of ndarray and None, optional
A location into which the result is stored. If provided, it must have a shape that the inputs broadcast to. If not provided or
None
, a freshly-allocated array is returned. A tuple (possible only as a keyword argument) must have length equal to the number of outputs.where : array_like, optional
Values of True indicate to calculate the ufunc at that position, values of False indicate to leave the value in the output alone.
**kwargs
For other keyword-only arguments, see the ufunc docs.
Returns: out : ndarray, int
Return
x1
with bits shiftedx2
times to the right.See also
-
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])
