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

    c = a ^ b;              // 49 = 0011 0001
Description | Compares two expressions bit by bit and returns 1 for a position bit if one compared postitions is 1. Returns 0 for that position bit if both compared positions are 0 or 1. 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 0 because both are 1 0 ^ 0 // Evaluates 0 because both are 0`
Syntax |
    expression1 ^ expression2
Parameters |
expression1 | any valid expression
expression2 | any valid expression
