The Bit API is for manipulating numbers using bitwise binary operations.
 Bit (API) | |
| Method name | Description |
| bit.blshift(int n, int bits) | Shifts a number left by a specified number of bits. |
| bit.brshift(int n, int bits) | Shifts a number right arithmetically by a specified number of bits. |
| bit.blogic_rshift(int n, int bits) | Shifts a number right logically by a specified number of bits. |
| bit.bxor(int m, int n) | Computes the bitwise exclusive OR of two numbers. |
| bit.bor(int m, int n) | Computes the bitwise inclusive OR of two numbers. |
| bit.band(int m, int n) | Computes the bitwise AND of two numbers. |
| bit.bnot(int n) | Computes the bitwise NOT of a number. |
The following functions used to exist in this API but no longer do:
| Bit (API) | |
| Method name | Description |
| bit.tobits(int n) | Converts a number to an array (numerically-indexed table) containing the corresponding binary bit values. |
| bit.tonumb(table bit_tbl) | Converts an array (numerically-indexed table) of 0 and 1 values representing a number in binary into that number. |
