public static member function (公共靜態成員函式)
<random>
static constexpr result_type min();
最小值
Returns the minimum value potentially returned by member operator(), which is the same as its base engine's minimum value. (返回成員operator()可能返回的最小值，該值與其基類引擎的最小值相同。)
返回值
base().min() (基類().min())
result_type (結果型別)is a member type, defined as an alias of the type of the numbers generated by the base engine. (是一個成員型別，定義為基類引擎生成的數字型別的別名。)
