Description:
------------
The Japanese translation of mt_srand()'s "ChangeLog Since 5.2.1" is not
correct.
It seems to have confused seeds and values.
Reproduce code:
---------------
http://www.php.net/manual/ja/function.mt-srand.php
The Mersenne Twister implementation in PHP now uses a new seeding
algorithm by Richard Wagner.
Identical seeds no longer produce the same sequence of values they did
in previous versions.
This behavior is not expected to change again, but it is considered
unsafe to rely upon it nonetheless.
Expected result:
----------------
PHP の Mersenne Twister 実装は、Richard
Wagner
による新たなシード生成アルゴリズムを使用するようになりました。
これまでのバージョンと同じシード値で同じ乱数列が生成されることはなくなりました。
この振る舞いが再び変わる見込みはありませんが、それに関わらずこの振る舞いに頼るのは安全ではありません。
Actual result:
--------------
PHP の Mersenne Twister 実装は、Richard
Wagner
による新たなシード生成アルゴリズムを使用するようになりました。
これまでのバージョンのように、同じ値のシーケンスで同じシードが生成されることはなくなりました。
この振る舞いが今後変わることはないでしょうが、この振る舞いに頼ってしまってはいけません。
