🔧 Functions#

You can find below all functions available in this module.

Complement to 2#

#bs.bitwise:two_complement

Compute the two’s complement of a number.

Inputs:

Score $bitwise.two_complement.value bs.in: Number to compute the two’s complement of.

Outputs:

Return | Score $bitwise.two_complement bs.out: The two’s complement of the number.

Compute and display the two’s complement of -12:

# Once
scoreboard players set $bitwise.two_complement.value bs.in -12
function #bs.bitwise:two_complement

# See the result
tellraw @a [{"text":"Two's complement of -12 = ","color":"#e0c7ff"},{"score":{"name":"$bitwise.two_complement","objective":"bs.out"}}]
