Lognand

Bitwise logical `nand' of two integers

When integers are viewed in their two's complement representation, lognand returns their bitwise logical `nand'.

The guard for lognand requires its arguments to be integers. Lognand is defined in Common Lisp. See any Common Lisp documentation for more information.

Function: lognand

(defun lognand (i j)
  (declare (xargs :guard (and (integerp i) (integerp j))))
  (lognot (logand i j)))
