These results evaluate to infinity, as the number returned by a 10,000,000 factorial is too large for a double-precision variable to contain.
估计这些结果会无限大，因为10,000,000的阶乘返回的数字对于双精度变量而言太大，以至超出了它包含的范围。
The variable $values is neither a node-set nor an IDN; it is just a sequence of atomic double-precision numbers.
变量 $values 既不是节点集也不是 IDN，仅仅是一个原子性的双精度数序列。
