result to machine 0;If the level code overflow (exceeds the maximum value indicated by the level code), the overflow flag is set. Example: Suppose X = 0. 0110011*211, Y = 0.1101101*2-10 (the numbers here are both binary )?? Calculate X + Y;Solution: [X] float: 0 1 010 1100110[Y] floating: 0 0 110 1101101Tail Number of the signed level code Step 1: Calculate the order difference: │ △e │ = | 1010-0110 | = 0100Step 2: lower order: the order code of Y is small, and the tail number of Y shifts four

Sensormanager is a class in Android that has a function getRotationMatrix that calculates the rotation matrix and then getOrientation obtains the direction of the device (heading angle, pitch angle, roll angle). function getRotationMatrix的源码如下所示，源码中虽然对该函数整体进行了解释，但是对代码中各个参数的计算没有说明，如为什么加速度的数值要和磁力计的数值做差乘。在网上各种搜索后，找到一段老外对这个问题的英文解释，很好的回答了上述问题。大意翻译（包括自己的理解）如下：加速度数值和磁力计数值均是向量，手机水平放置时，加速度读数实际上就是重力向量，方向是竖直朝下的；磁力计表示本地的磁场，不考虑环境影响及磁偏角的话，认为磁场方向是水平南北朝向的。因此，代码中首先对加速度和磁力计数据做了一个差乘，得出一个水平东西方向的向量（差乘的定义）。经过这个运算，本来只

started with this interface, all you need to do is draw the object using the Render method. It is implemented by a line class that takes advantage of 4 coordinates: The start and end of the X value, the start and end of the Y value. It also has a color. When Render is called, the object draws a line of color specified by the name from Sx,sy to Ex,ey. The code for this library is shown in Listing 1. Listing 1. Basic Graphics Library

. graphic environment and graphic object interface The GraphicsEnvironment class saves the graphic objects and a set of colors, including the width and height. The saveAsPng method outputs the current image to a specified file. GraphicsObject is a required interface for any graphic object. To start using this interface, you must use the render method to draw this object. It is implemented by a Line class. it uses four coordinates: the x value of start and end, and the y value of start and end

It's useless to use a good formula ... Think in fact very simple, first of all should be analyzed, because each add an LCM is greater than or equal to any one of the number, then my LCM plus which number above, that number will become big, so think, we know, each (x, y) corresponds to a situation.The second point is that the formula, we can think about, is not the number can be split, we foundA=x*k,b=y*k, where K=GCD (A, A, b) and X and Y coprime, so that we can push (x*k,y*k) to (x*k,x*y+x*y*k)
