零基础小白学触动 - 05 - 触动常用函数 点击 滑动 原理 其实都可以分解成 按下=》 等待一定时间或者移动动作=》 松开 点击： tSLib库的函数tap(x,y) 后面还有2个参数 可以自己看手册 https://www.zybuluo.com/miniknife/note/293935#函数tap-点击 滑动 moveTo(x1,y1,x2,y2,step) 详细的 https://www.zybuluo.com/miniknife/note/293935#函数moveto-滑动 ？如何实现精确滑动 https://zimaoxy.com/b/t-860-1-3.html 深入研究 暂时还没理解思路 而触动手册里面给的例子测试过 无法做到完美的精确滑动 就不用了 还有其他模式的滑动 在当前滑动无效的情况下 延时 mSleep() 坐标初始化函数 init(0) 没什么说的 0是home在下 1是home在右 2是home在左 脚本开始要坐标初始化下 而且不能把init() 放到其他文件然后require导入 是对main.lua无效的 血泪的教训 小知识：require 调用文件的使用注意 require会自动判断当前原码是否已经载入该文件 如果已经载入这个文件就不会再继续载入 给我们一个省事的用法 无法叠加require 比如说 我在主脚本里面调用自己的模版

How do I prevent my double value from being rounded when converting to a string? I have tried both Convert.ToString and ToString() with the same result. For example my double may look something like 77.987654321 , and the two strings conversions convert to to 77.98765 . I need to keep the precision of the value as is. By default the .ToString() method of Double returns 15 digits of precision. If you want the full 17 digits that the double value holds internally, you need to pass the "G17" format specifier to the method. String s = value.ToString("G17"); Sourced from the MSDN docs : By default,

Is it good or bad practice auto-generating toString methods for some simple classes? I was thinking of generating something like below where it takes the variable names and produces a toString method that prints the name followed by its value. private String name; private int age; private double height; public String toString(){ return String.format("Name: %s Age: %d Height %f", name, age, height); } Eclipse 3.5.2 (and possibly earlier versions) already provides this feature. If you right-click within the editor, you'll find it under Source -> Generate toString()... To answer your question

How to convert double to string without the power to 10 representation (E-05) double value = 0.000099999999833333343; string text = value.ToString(); Console.WriteLine(text); // 9,99999998333333E-05 I'd like the string text to be 0.000099999999833333343 (or nearly that, I'm not doing rocket science:) I've tried the following variants Console.WriteLine(value.ToString()); // 9,99999998333333E-05 Console.WriteLine(value.ToString("R20")); // 9,9999999833333343E-05 Console.WriteLine(value.ToString("N20")); // 0,00009999999983333330 Console.WriteLine(String.Format("{0:F20}", value)); // 0

I have a list of strings that can contain a letter or a string representation of an int (max 2 digits). They need to be sorted either alphabetically or (when it is actually an int) on the numerical value it represents. Example: IList<string> input = new List<string>() {"a", 1.ToString(), 2.ToString(), "b", 10.ToString()}; input.OrderBy(s=>s) // 1 // 10 // 2 // a // b What I would want is // 1 // 2 // 10 // a // b I have some idea involving formatting it with trying to parse it, then if it is a successfull tryparse to format it with my own custom stringformatter to make it have preceding zeros.

In C#. I have a double (which I've extracted from a database) that has 20 digit precision. In Visual Studio (using QuickWatch) I can see the value of the double to be = 0.00034101243963859839. I want to display this value in a textbox and then have it be the same value when I take it out and convert it back into a double. But I always lose the last two digits I've tried the following: double d = 0.00034101243963859839; string s = d.ToString(); string s2 = d.ToString("F20"); string s3 = d.ToString("0.00000000000000000000"); -- 20 0's string s4 = (d*100d).ToString(); In these cases: s = 0
