Hi all, I once heard that using math.randomseed(os.clock() * 100000000000) is better than using math.randomseed(os.clock()). Is this true? If so, why? I looked through the Lua documentation regarding the math library but did not see any use case other than math.randomseed(os.clock()).

os.clock() returns not an integer, but a fractional. math.randomseed()receives an integer as input
https://www.lua.org/source/5.1/lmathlib.c.html
static int math_randomseed (lua_State *L) {
srand(luaL_checkint(L, 1));
return 0;
}

So multiplying by a large constant “converts” the decimal to an integer. This is better than simply using math.floor() or math.ceil() to convert to an integer because we want a seed that is constantly changing rather than changing only once per second.
Thank you.
There is also socket.gettime(). I tend to use it like this to make subsequent reasonably random numbers:
math.randomseed(socket.gettime()*10000)
math.random()
math.random()
math.random()
