Revision history [back]

Lua treats all number variables as floats. Forcing a cast to integer with math.floor gave better results.
Modulo (%) returns a non-integer if passed a non-integer so may need wrapped also.
Maybe better to rework the math logic if bit positions are the target?

2.1 – Values and Types

There are eight basic types in Lua: nil, boolean, number, string, function, userdata, thread, and table.

Number represents real (double-precision floating-point) numbers.

   cmdindex = 10
   tox_flag = 65

    tox_flag_reliablesn = math.floor(tox_flag/64)

    tox_flag_reliablesn = tox_flag_reliablesn%2

    tox_flag_frag = math.floor(tox_flag/128)
    print("tox_flag_frag =", tox_flag_frag)

    tox_flag_life =  math.floor(tox_flag/32)

    tox_flag_life = (tox_flag_life%2

3.4.1 – Arithmetic Operators

Modulo is defined as

 a % b == a - math.floor(a/b)*b

That is, it is the remainder of a division that rounds the quotient towards minus infinity.
