@ -58,6 +58,11 @@ make sure that both the upper & lower bound
as well as their difference are within the C `int` range -
otherwise you may get overflows & errors.
WARNING: This is not portable; different builds on different platforms will produce different random numbers.
PUC Lua 5.1 builds use a system-provided random generator.
LuaJIT builds use LuaJIT's PRNG implementation.
Do not use `math.random` in mapgen, for example.
TIP: Use `math.random` as your go-to versatile "non-deterministic" random source.
