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?

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
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.

The function string.format is a powerful tool when formatting strings, ...
Changing the debug line from integer (%d) to floats (%f) :
local message = string.format("line = %f : value1 = %f value2 = %f value3 = %f value4 = %f", lineno, value1, value2, value3, value4)
shows that the variables are non-zero values.
