public member function （公共成員函式）
<random>
result_type operator()();
生成隨機數
Returns a new random number. （返回一個新的隨機數。）
The engine's transition algorithm invokes the base engines's （引擎的轉移演算法呼叫了base引擎的）operator()member as many times as needed to obtain enough significant bits to construct a random value. （成員，根據需要多次呼叫，以獲得足夠的有效位來構造一個隨機值。）
The generation algorithm joins the bits obtained above to generate a single value, which is returned by this member function. （生成演算法將上面獲得的位連線起來以生成單個值，該值由該成員函式返回。）
返回值
A new random number. （一個新的隨機數。）
result_type （結果型別）是一種成員型別，定義為由 base 引擎生成的數字型別的別名。
