bitwise_left_shift¶

paddle. bitwise_left_shift ( x, y, is_arithmetic=True, out=None, name=None ) [source]

Apply bitwise_left_shift on Tensor X and Y .

\[Out = X \ll Y\]

Note

paddle.bitwise_left_shift supports broadcasting. If you want know more about broadcasting, please refer to please refer to Introduction to Tensor .

Parameters

• x (Tensor) – Input Tensor of bitwise_left_shift . It is a N-D Tensor of uint8, int8, int16, int32, int64.

• y (Tensor) – Input Tensor of bitwise_left_shift . It is a N-D Tensor of uint8, int8, int16, int32, int64.

• is_arithmetic (bool, optional) – A boolean indicating whether to choose arithmetic shift, if False, means logic shift. Default True.

• out (Tensor, optional) – Result of bitwise_left_shift . It is a N-D Tensor with the same data type of input Tensor. Default: None.

• name (str, optional) – The default value is None. Normally there is no need for user to set this property. For more information, please refer to Name.

Returns

Result of bitwise_left_shift . It is a N-D Tensor with the same data type of input Tensor.

Return type

Tensor
