README

Xoroshiro128++ random number generator, made for use in PocketMine-MP.

Usage

use pocketmine\xoroshiro\Xoroshiro128PP;

$random = Xoroshiro128PP::fromSeed($seed);
$random->nextLong();   // signed 64-bit
$random->nextFloat();  // [0, 1)

• Xoroshiro128PP - the generator. fromSeed() expands one 64-bit seed into the 128-bit state the way Minecraft does; the constructor takes the two halves of the state directly.
• SplitMix64 - the finaliser (Stafford variant 13) that seeding is built on, exposed because position hashes often need it on its own.

Requirements

• PHP 8.1 or newer, 64-bit
• ext-gmp
