Bit shifting in lua

[Brutile]

Is there a way to use bit shifting in lua?

i.e. 1<<8 to get 256

[Guppy]

not as easily but it can be done;

I think LE uses lua 5.2?

Looks easy to me... its already inherent to LE's current lua implementation as long as sandboxing is disabled.

This appears to be the list of available bitwise operations:

bit.tobit(x) -- normalize number to the numeric range of

bit.tohex(x[,n]) -- convert x to hex with n digits (default 8)

bit.bnot(x) -- bitwise not of x

bit.band(x1[,x2...]) -- bitwise and of x1, x2, ...

bit.bor(x1[,x2...]) -- bitwise or of x1, x2, ...

bit.bxor(x1[,x2...]) -- bitwise xor of x1, x2, ...

bit.lshift(x, n) -- left-shift of x by n bits

bit.rshift(x, n) -- logical right-shift of x by n bits

bit.arshift(x, n) -- arithmetic right-shift of x by n bits

bit.rol(x, n) -- left-rotate of x by n bits

bit.ror(x, n) -- right-rotate of x by n bits

bit.bswap(x) -- byte-swap of x (little-endian <-> big-endian)
