From ComputerCraft Wiki

Function bit.band | |

Computes the bitwise inclusive OR of two numbers | |

Syntax | bit.band(int m, int n) |

Returns | int 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 |
