Function Description

  • Operator function: computes the bitwise AND of each element in the input tensor and the corresponding element of the other input (a tensor or a scalar). The inputs must be integer or BOOL variables. When the inputs are BOOL, the logical AND result is computed.

  • Computation formula:

    • When other is a tensor:

      outi=selfi&otheriout_i = self_i \& other_i

    • When other is a scalar:

      outi=selfi&otherout_i = self_i \& other

Parameter Description

Parameter Name Input/Output/Attribute Description Data Type Data Format
self Input Input self in the formula. INT16, UINT16, INT32, INT64, INT8, UINT8, UINT32, UINT64, BOOL ND
other Input Input other in the formula. INT16, UINT16, INT32, INT64, INT8, UINT8, UINT32, UINT64, BOOL ND
out Output Output out in the formula. BOOL, INT8, INT16, UINT16, INT32, UINT32, INT64, UINT64, UINT8, FLOAT, FLOAT16, DOUBLE, BFLOAT16, COMPLEX64, COMPLEX128 ND
  • Atlas A3 products, Atlas A2 products, Atlas inference products, and Atlas training products: the data types of self and other do not support UINT32 or UINT64; the data type of out does not support UINT32, UINT64, COMPLEX64, or COMPLEX128.

Constraint Description

  • The data types of the inputs must satisfy the data type deduction rules (see deduction relationship), and the deduced data types must be within the supported range.
  • Each API is deterministic by default. For specific constraints, refer to the corresponding aclnn API documentation.
