🔧 Functions#
You can find below all the function available in this module.
logical AND#
#bs.bitwise:and
Computes the bitwise conjunction of the two input numbers
- Inputs
- (score)
$bitwise.and.0 bs.in The first operand \(a\)
- (score)
$bitwise.and.1 bs.in The second operand \(b\)
Negative input
If one of the inputs is negative, the operation will be done between the first operand and the two’s complement of the second
- (score)
- Outputs
- (score)
$bitwise.and bs.out The result of the operation = \(a \times b\)
- (score)
- Example
Calculate and display \(-9 \times 57\)
# Once scoreboard players set $bitwise.and.0 bs.in -9 scoreboard players set $bitwise.and.1 bs.in 57 function #bs.bitwise:and tellraw @a [{"text":"-9 & 57 = ", "color": "dark_gray"},{"score":{"name":"$bitwise.and", "objective": "bs.out"}, "color": "gold"}]

logical OR#
#bs.bitwise:or
Computes the bit to bit disjunction of the two input numbers
- Inputs
- (score)
$bitwise.or.0 bs.in The first operand \(a\)
- (score)
$bitwise.or.1 bs.in The second operand \(b\)
Negative input
If one of the inputs is negative, the operation will be done between the first operand and the two’s complement of the second
- (score)
- Outputs
- (score)
$bitwise.or bs.out The result of the operation = \(a + b\)
- (score)
- Example
Calculate and display \(-9 + 57\).
# Once scoreboard players set $bitwise.or.0 bs.in -9 scoreboard players set $bitwise.or.1 bs.in 57 function #bs.bitwise:or tellraw @a [{"text":"-9 | 57 = ", "color": "dark_gray"},{"score":{"name":"$bitwise.or", "objective": "bs.out"}, "color": "gold"}]
