实验2 计算器设计文档姓名： 梁姣 学号： 07220111 班级： 计本071 日期：20081009实验目的和要求1. 设计背景设计拥有简单的计算功能，方便计算简单的计算题。方便用户的使用。2. 设计功能具有一般计算功能，能进行基本的加减乘除运算，还具有求根号，倒数等功能。特点是能进行不同进制的运算和不同进制间的转换。3. 模块分解该计算器分为3个模块，分别是Textbox：显示区：显示数字和计算结果的功能button：计算区：提供运算符和数字，与用户交互进行运算radioButton：转换区： 用于进制之间的转换4. 设计界面标准型 科学型5. 按键定义Button1button29为1到F相应的数字键和运算符RadioButton14 用于各种进制之间的转换Textbox1 为显示区，显示输入和计算结果6. 其他定义 int command = 0; string stringbefore; /存储算数运算符按下之前的字符串。 string stringlast; /存储算数运算符按下之后的字符串。 long metadata; /进制转换时存储中间值。 double doublebefore = 0; /存储算数运算符按下之前的数字。 double doublelast = 0; /存储算数运算符按下之后的数字。 double result = 0; /存储运算之后的数字值。 bool flag = true ;/判断是否已经按过了算数运算符。实验内容u 设计思路与源程序普通型：using System;using System.Collections.Generic;using System.ComponentModel;using System.Data;using System.Drawing;using System.Text;using System.Windows.Forms;namespace 计算器实验 public partial class Form1 : Form public Form1() InitializeComponent();
