Function band
Performs a bitwise 'and' operation of the {number} arguments by taking the binary representation of each of the numbers and performing the logical and operation on each of the bits.
Logical "and" Table
| Bit1 | Bit2 | Result |
| 0 | 0 | 0 |
| 0 | 1 | 0 |
| 1 | 1 | 1 |
Usage
[h: val = band(num, num, ...)]
[h: val = bitwiseand(num, num, ...)]Examples
[r: band(1,0)]Returns 0.
[r: band(1,1)]Returns 1.
[r: band(3, 5]Returns 1. 3 in binary is 011 and 5 in binary is 101, the bitwise 'and' of these values is 001 in binary which is 1 in decimal.
[r: band(20, 12)]Returns 4. 20 in binary is 10100 and 12 in binary is 01100, the bitwise 'and' of these values is 00100 in binary which is 4 in decimal.
