The identity and nature of the values of each of these variables is implementation-dependent, except that it must be distinct from each of the values of the others, and it must be a valid first argument to the function boole.
Each of these constants has a value which is one of the sixteen possible bit-wise logical operation specifiers.
(boole boole-ior 1 16) → 17 (boole boole-and -2 5) → 4 (boole boole-eqv 17 15) → -31
