[HELP] Random number problem

[..:D&G:..]

Hello guys, I am making a login system and I want to generate a random salt from some numbers using math.random

local salt = math.random(106060023000, 9919995299949969) 

The problem is that I get a negative number like -29404583

Any ideas?

Thanks

Maybe replace it to random string?

You can use math.abs to make it positive number.

You can only pass 2^31-1 bit integer arguments in the math class.

This means the maximum number you can represent is: 2147483647

You're getting a negative value because you're getting an integer overflow, meaning the value you're trying to represent is higher than the value I've just mentioned and therefore the bit signal is affected.

The solution for your problem is simple (assuming you really need a number that high):

  
local a = "" 
for k = 1, 12 do 
   a = a .. tostring(math.random(0,9)) 
end

as TAPL said try to use math.abs.

local salt = math.random(106060023000, 9919995299949969) 
local salt2 = math.abs(tonumber(salt))
