math.random
Returns a random number between the values provided. When called without arguments, returns a uniform pseudo-random real number in the range [0,1]. When called with an integer number m, math.random returns a uniform pseudo-random integer in the range [1, m]. When called with two integer numbers m and n, math.random returns a uniform pseudo-random integer in the range [m, n].
LuaJIT uses a Tausworthe PRNG with period 2^223 to implement math.random and [math.randomseed(#randomseed).
When called without arguments it generates 52 pseudo-random bits for every call. The result is uniformly distributed between 0.0 and 1.0. It's correctly scaled up and rounded for math.random(n [,m]) to preserve uniformity.
Important: Neither this nor any other PRNG based on the simplistic math.random API is suitable for cryptographic use.
