Question

总是一个是四个数小于一的数字的结果。

我将数字更改为十进制并浮动
我用数学，截断
我在计算中的每个数字之前写了两倍

总和的结果仍然是一个

这是我的代码，我在代码中添加了注释来代替我的代码

尝试使用Implicit typing：var来声明您的varibales 我试过你说的话;我有逻辑结果：这是一个示例exmaple：

 public class Program
    {
        public static void Main(string[] args)
        {
            var p1 = 0.120336943441637;
            var p5 = 0.01323706377858;
            var p9 = 0.120336943441637;
            var p13 = 0.120336943441637;
            var sum = p1 + p5 + p9 + p13;
            Console.WriteLine(sum);
        }

    }

结果= 0.374247894103491
