mathRNG method
Math.Random()-based RNG. All platforms, fast, not cryptographically strong. Optional Seed passable.
Implementation
static List<int> mathRNG({int seed = -1}) {
var rand, b = new List<int>(16);
var _rand = (seed == -1) ? new Random() : new Random(seed);
for (var i = 0; i < 16; i++) {
if ((i & 0x03) == 0) {
rand = (_rand.nextDouble() * 0x100000000).floor().toInt();
}
b[i] = rand >> ((i & 0x03) << 3) & 0xff;
}
return b;
}
