Name |  | ### | (bitwise OR)
Examples |  |
    unsigned int a = 60;	// 60 = 0011 1100
    unsigned int b = 13;	// 13 = 0000 1101
    unsigned int c = 0;

    c = a | b;              // 61 = 0011 1101
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`
Syntax |  |
    expression1 | expression2
Parameters |  |
expression1 |  | any valid expression
expression2 |  | any valid expression
Returns |  |
