local bit = require("bit");

Refer to the official documentation from LuaJIT for more details.

bit.bnot( x )

Returns the bitwise not of x.

bit.band( x, y )

Returns the bitwise and of x and y.

bit.bor( x, y )

Returns the bitwise or of x and y.

bit.bxor( x, y )

Returns the bitwise exclusive or of x and y.

bit.lshift( x, n )

Returns the bitwise logical left shift of x of n steps.

bit.rshift( x, n )

Returns the bitwise logical right shift of x of n steps.

bit.arshift( x, n )

Returns the bitwise arithmetic right shift of x of n steps.

bit.rol( x, n )

Returns the bitwise left rotation of x of n steps.

bit.ror( x, n )

Returns the bitwise right rotation of x of n steps.

bit.tohex( x [,n] )

Helper function to convert a number to a hex string.

bit.tobit( x )

Helper function to normalize values
