Vitalik Buterin: 更有趣的是 tan(int) 不是随机数生成器。数据中有迷人的模式。一种看待它的方法是：如果 tan(x) 非常高，则 x 非常接近 90′ 或 270′ 角。因此，如果 tan(x) 和 tan(y) 很高，则 tan(x + 2y) 也很高。

原推：What’s even more interesting is that tan(int) is *not* a random number generator. There’s fascinating patterns in the data.

One way to look at it is: if tan(x) is very high, x is very close to a 90′ or 270′ angle. So if tan(x) and tan(y) are high, tan(x + 2y) is also high.
