torch.bitwise_left_shift

torch.bitwise_left_shift(input, other, *, out=None)Tensor

Computes the left arithmetic shift of input by other bits. The result will have the same dtype as input.

The operation applied is:

outi=inputi×2otheri\text{out}_i = \text{input}_i \times 2 ^ {\text{other}_i}
Parameters
  • input (Tensor or Scalar) – the first input tensor

  • other (Tensor or Scalar) – the second input tensor

Keyword Arguments

out (Tensor, optional) – the output tensor.

Example

>>> torch.bitwise_left_shift(torch.tensor([-1, -2, 3], dtype=torch.int8), torch.tensor([1, 0, 3], dtype=torch.int8))
tensor([-2, -2, 24], dtype=torch.int8)
