| ===Usage===
| |
| <source lang="mtmacro" line>
| |
| [h: val = band(num, num, ...)] | |
| [h: val = bitwiseand(num, num, ...)] | |
| </source>
| |
| | |
| ===Examples===
| |
| <source lang="mtmacro" line>
| |
| [r: band(1,0)]
| |
| </source>
| |
| Returns 0.
| |
| | |
| <source lang="mtmacro" line>
| |
| [r: band(1,1)]
| |
| </source>
| |
| Returns 1.
| |
| | |
| <source lang="mtmacro" line>
| |
| [r: band(3, 5]
| |
| </source>
| |
| 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.
| |
| | |
| <source lang="mtmacro" line>
| |
| [r: band(20, 12)]
| |
| </source>
| |
| 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.
