Lua语言的16进制转b进制

local i
s = "123ABC"
sum = 0
for i = 1, #s, 1 do
    local t = string.byte(s, i)
	print("t =", t)
    if(t >= 48 and t <= 48 + 9) then
        t = t - 48
    elseif(t >= 65 and t <= 70) then
        t = t - 55
    end
    sum = sum * 16 + t
end
print("sum = "..sum)
tmp = ""
while(sum > 0) do
	local c = sum % 8
	tmp = string.char(c + 48)..tmp
	sum = (sum - c) / 8
end

print(tmp)
