jax.numpy.right_shift#
jax.numpy.right_shift(x1, x2, /)[source]#
Right shift the bits of x1 to the amount specified in x2.
JAX implementation of numpy.right_shift.
Parameters:
- x1 (ArrayLike) – Input array, only accepts unsigned integer subtypes
- x2 (ArrayLike) – The amount of bits to shift each element in
x1to the right, only accepts integer subtypes
Returns:
An array-like object containing the right shifted elements of x1 by the amount specified in x2, with the same shape as the broadcasted shape ofx1 and x2.
Return type:
Note
If x1.shape != x2.shape, they must be compatible for broadcasting to a shared shape, this shared shape will also be the shape of the output. Right shifting a scalar x1 by scalar x2 is equivalent to x1 // 2**x2.
Examples
def print_binary(x): ... return [bin(int(val)) for val in x]
x1 = jnp.array([1, 2, 4, 8]) print_binary(x1) ['0b1', '0b10', '0b100', '0b1000'] x2 = 1 result = jnp.right_shift(x1, x2) result Array([0, 1, 2, 4], dtype=int32) print_binary(result) ['0b0', '0b1', '0b10', '0b100']
x1 = 16 print_binary([x1]) ['0b10000'] x2 = jnp.array([1, 2, 3, 4]) result = jnp.right_shift(x1, x2) result Array([8, 4, 2, 1], dtype=int32) print_binary(result) ['0b1000', '0b100', '0b10', '0b1']
