Description

The function int32-logand is the bitwise logical 'and' operator for int32 objects.

The function int32-logandc1 is the bitwise logical operator for int32 objects which 'ands' the complement of x with y.

The function int32-logandc2 is the bitwise logical operator for int32 objects which 'ands' x with the complement of y.

The function int32-logbitp is the test for int32 objects which returns t if if the bit at index index in x is 1, and nil if it is 0.

The function int32-logeqv is the bitwise logical operator for int32 objects which returns the complement of the 'exclusive or' of x and y.

The function int32-logior is the bitwise logical 'inclusive or' operator for int32 objects.

The function int32-lognand is the bitwise logical operator for int32 objects which returns the complement of the 'and' of x and y.

The function int32-lognor is the bitwise logical operator for int32 objects which returns the complement of the 'inclusive or' of x and y.

The function int32-lognot is the bitwise logical operator for int32 objects which returns the complement of its argument x.

The function int32-logorc1 is the bitwise logical operator for int32 objects which 'inclusive ors' the complement of x with y.

The function int32-logorc2 is the bitwise logical operator for int32 objects which 'inclusive ors' x with the complement of y.

The function int32-logtest is the bitwise test for int32 objects which returns t if any of the bits designated by 1 in x is 1 in y, and returns nil otherwise.

The function int32-logxor is the bitwise logical 'exclusive or' operator for int32 objects.

See the section Fast 32-bit arithmetic for more information about the INT32 API.
