API fastrandom

Returns a random number within the specified interval.
 rand = fastrandom([ [low, ] high])
==Arguments==
:;low: - lower integer limit on the returned random value.
:;high: - upper integer limit on the returned random value.
==Returns==
:;rand: - Generated random value. If no arguments were specified, the value is a uniformly-distributed decimal between 0 (inclusive) and 1 (exclusive). Otherwise, returns a uniformly-distributed integer between low (1 if not specified) and high, both bounds inclusive.
==Details==
* This function uses C's rand function as a random number generator. On the Windows client, the implementation of random(high) is equivalent to the following, which is not cryptographically secure: it is possible to derive its internal state from a few samples of its output and correctly predict the results of subsequent calls.
 local state = 0 -- initialized by seeding
 function random(high)
 state = (state * 214013 + 2531011) % 2^32;
 local rand = math.floor(state / 2^16) % 2^15;
 return 1 + math.floor(rand / 0x7fff * high)
 end
* Lua's math.randomseed is not available in World of Warcraft; the random number generator is instead seeded by the client at startup.
