macros:Functions:band

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.
