Function bit.bor | |
Computes the bitwise inclusive OR of two numbers | |
Syntax | bit.bor(number m, number n) |
Returns | number the value of m OR n |
Part of | ComputerCraft |
API | bit |
Examples
Example | |
OR the number 18 (10010) with the number 3 (00011), yielding 19 (10011) | |
Code |
print(bit.bor(18, 3)) |
Output | 19 |
Explanation
All bit operations operate in binary numeral system [1]. An inclusive OR operation between two bits yields a 1 if either of the bits is 1 and a 0 if they are both 0. This function produces an output by computing the OR of each bit of its two inputs independently. So, for the example above:
Bit index: | 4 | 3 | 2 | 1 | 0 |
---|---|---|---|---|---|
Input 1 (18): | 1 | 0 | 0 | 1 | 0 |
Input 2 (3): | 0 | 0 | 0 | 1 | 1 |
Calculation: | 18 has a 1 | Both 0 | Both 0 | Both 1 | 3 has a 1 |
Output (19): | 1 | 0 | 0 | 1 | 1 |
