不是真心热爱的话，枯燥，繁杂，千篇一律，不能获得所期望的价值实现。

已兑， thanks

@nashge 嗯，是的呢。主要就是想弄清楚第二种方法。

看来还是要 google 啊。

In comparison operations, positive infinity is larger than all values except itself and NaN, and negative infinity is smaller than all values except itself and NaN. NaN is unordered: it is not equal to, greater than, or less than anything, including itself. x == x is false if the value of x is NaN. You can use this to test whether a value is NaN or not, but the recommended way to test for NaN is with the isnan function (see Floating Point Classes). In addition, <, >, <=, and >= will raise an exception when applied to NaNs.
