The Bit API is for manipulating numbers using bitwise binary operations.
All of these functions treat the numbers as 32-bit integers, and will raise an error if an input number is greater than 4,294,967,295.
 Bit (API) | ||
|---|---|---|
| Function | Return values | Description |
| bit.blshift(number n, number bits) | number value | Shifts a number left by a specified number of bits. |
| bit.brshift(number n, number bits) | number value | Shifts a number right arithmetically by a specified number of bits. |
| bit.blogic_rshift(number n, number bits) | number value | Shifts a number right logically by a specified number of bits. |
| bit.bxor(number m, number n) | number value | Computes the bitwise exclusive OR of two numbers. |
| bit.bor(number m, number n) | number value | Computes the bitwise inclusive OR of two numbers. |
| bit.band(number m, number n) | number value | Computes the bitwise AND of two numbers. |
| bit.band(number n) | number value | Computes the bitwise NOT of a numbers. |

| Return | Method name | Description |
| table bit_tbl | bit.tobits(number n) | Converts a number to an array (numerically-indexed table) containing the corresponding binary bit values. |
| number value | bit.tonumb(table bit_tbl) | Converts an array (numerically-indexed table) of 0 and 1 values representing a number in binary into that number. |
