| Description | Compares two expressions bit by bit and returns 1 for a position bit if one or both compared postitions are 1. Returns 0 for that position bit if both compared positions are 0. The following list shows all possible combinations: 1 | 0 // Evaluates 1 because the first is 1 0 | 1 // Evaluates 1 because the second is 1 1 | 1 // Evaluates 1 because both are 1 0 | 0 // Evaluates 0 because both are 0 |
