I'm new to Lua and have been struggling...

does anyone know how to convert numbers to bit arrays Or binary strings?

For example :
123456 =11110001001000000

Thanks
Rob

divide new number by 2 -> second last bit
and so on

Code: Select allfunction toBits(x)
     bits = {}
     repeat
          table.insert (bits, 1, x%2)
          x = x/2
     until x==0
     return bits
end
