math.random() allways retuns 0.7942

[kike]

Hi, 

I noticed that when I use the math.random() with out arguments returns allways the same value, if arguments are used return the maximun.

example: 

log(math.random())


returns:

* number: 0.794206292431241

what I am doing wrong?

Thanks!!

Can I have the math.random function output random numbers, letters, and special characters?

Use this. Modify the character list as needed.

Code:

123456789101112131415161718192021

function randompassword(length)   local characters = '0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz'   local max = #characters - 1   local buffer = {}   length = length or 12   local ts, tu = os.microtime()   math.randomseed(ts * 1e6 + tu)   for i = 1, length do     local rnd = math.random(1, max)     buffer[ i ] = characters:sub(rnd, rnd)   end   return table.concat(buffer) end length = 8 password = randompassword(length) log(password)

thank you very much
