System.out.println(Double.isNaN(Double.longBitsToDouble(0x7ff0000000000011L))); } 再看看这边的解释：Double.NaN...= Double.NaN 还有一点需要注意：在将一个float的NaN窄化转换为整数类型T（T限于int或long类型之一）的时候，那转换结果就是int或long类型的0；而double类型的NaN
这就要设计一个精度了，我们设为 1e-7 二、java代码，sqrt函数 public static double sqrt(double c){ if(c < 0) return Double.NaN
