1 题目要求
仿照Windows系统自带计算器做的一个小型科学计算器。 2 功能需求
整个系统具有的功能：响应各个数字键，实现加、减、乘、除、x^y、lnx、x!、sinx、cosx、tanx、二进制、二进制转换八进制、清空、求倒数等基本功能；
3 总体设计 3.1 系统模块
自然对数
函数和数据结构设计流程
科学计算器的参考源代码
1)在对话框类中定义用到的变量： double Buffer; //放显示结果 double Number1; //放第一个数 double Number2; //放第二个数 double Answer; //放结果
long Number1_N; //放第一个数的整数部分 long Number1Temp; //小数位临时变量 long Number2Temp; //小数位临时变量
long Number2_N; //放第二个数的整数部分
double Number1_Point;//放第一个数的小数部分 double Number2_Point;//放第二个数的小数部分 char Operater; //放操作数
short int OperaterFlag; //操作数的标志
short int WhichNumFlag; //输入那个数的标志 bool FigureFlag ; //是否按下等号的标志 bool Num1PointFlag; //数一小数的标志 bool Num2PointFlag; //数二小数的标志 short int OverFlag; //溢出标志
long Number1_PointBit; //第一个数小数位数 long Number2_PointBit; //第二个数小数位数 bool signFlag; //前一位是操作数
2）在对话框类的定义中添加下列函数声明：
afx_msg void OnSysCommand(UINT nID, LPARAM lParam); afx_msg void OnPaint();
afx_msg HCURSOR OnQueryDragIcon(); afx_msg void OnHEX();
afx_msg void OnButton1(); afx_msg void OnButton2(); afx_msg void OnButton3(); afx_msg void OnButton4(); afx_msg void OnButton5(); afx_msg void OnButton6(); afx_msg void OnButton7(); afx_msg void OnButton8(); afx_msg void OnButton9(); afx_msg void OnButton0(); afx_msg void Onpoint();
afx_msg void Onpositivenegative(); afx_msg void Onadd(); afx_msg void Onsub(); afx_msg void Onmul();
afx_msg void Ondiv(); afx_msg void Onmod(); afx_msg void Onsprt();
afx_msg void OnPrescribing(); afx_msg void Onfigure(); afx_msg void OnCe(); afx_msg void OnPi(); afx_msg void Onexp(); afx_msg void Onsin(); afx_msg void Oncos(); afx_msg void Ontan(); afx_msg void Onlog(); afx_msg void Onln();
afx_msg void Onallmul();
3）在对话框的可执行文件的消息映射中添加如下代码：
ON_BN_CLICKED(IDC_BUTTON1, OnButton1)
ON_BN_CLICKED(IDC_BUTTON2, OnButton2) ON_BN_CLICKED(IDC_BUTTON3, OnButton3) ON_BN_CLICKED(IDC_BUTTON4, OnButton4) ON_BN_CLICKED(IDC_BUTTON5, OnButton5) ON_BN_CLICKED(IDC_BUTTON6, OnButton6) ON_BN_CLICKED(IDC_BUTTON7, OnButton7) ON_BN_CLICKED(IDC_BUTTON8, OnButton8) ON_BN_CLICKED(IDC_BUTTON9, OnButton9) ON_BN_CLICKED(IDC_BUTTON0, OnButton0) ON_BN_CLICKED(IDC_point, Onpoint)
ON_BN_CLICKED(IDC_positive_negative, Onpositivenegative) ON_BN_CLICKED(IDC_add, Onadd) ON_BN_CLICKED(IDC_sub, Onsub) ON_BN_CLICKED(IDC_mul, Onmul) ON_BN_CLICKED(IDC_div, Ondiv) ON_BN_CLICKED(IDC_mod, Onmod) ON_BN_CLICKED(IDC_sprt, Onsprt)
ON_BN_CLICKED(IDC_Prescribing, OnPrescribing) ON_BN_CLICKED(IDC_figure, Onfigure) ON_BN_CLICKED(IDC_CE, OnCe) ON_BN_CLICKED(IDC_PI, OnPi)
ON_BN_CLICKED(IDC_exp, Onexp) ON_BN_CLICKED(IDC_sin, Onsin) ON_BN_CLICKED(IDC_cos, Oncos) ON_BN_CLICKED(IDC_tan, Ontan) ON_BN_CLICKED(IDC_log, Onlog) ON_BN_CLICKED(IDC_ln, Onln)
ON_BN_CLICKED(IDC_allmul, Onallmul)
4）在对话框的构造函数中初始化变量 Number1=0; Number1_N=0; Number1_Point=0; Number1_PointBit=1; Num1PointFlag=0; Number1Temp=0; Number2=0; Number2_N=0;
Number2_Point=0; Number2_PointBit=1; Num2PointFlag=0; Number2Temp=0; Answer=0;
FigureFlag=0; OperaterFlag=0; WhichNumFlag=1; OverFlag=0; Buffer=0;
Operater='#'; signFlag=0;
5）为对话框添加计算函数用于计算 void CCaculate3_0Dlg::OnButton1() {
// TODO: Add your control notification handler code here signFlag=0; OverFlag++;
if(WhichNumFlag==1) {
if(Num1PointFlag==0) {

测试与实现
1.计算 100的各种三角函数值
结果：-0.[1**********](sin) 0.[1**********]7(cos) -0.[1**********](tan)
计算 20的其它运算值
结果：2.[1**********]3（In） 0.05(倒数) 4.[1**********]9（根号）
总结
在大学学习C语言已有一个学期之久，已经感觉C语言是一门不好学的一门课程，然而还是为了自己能编一些比较简单的程序窃喜的，但经过课程设计才知道原来C语言比我想象的要难的多，一个简单的计算器都令我苦不堪言，更别说将来工作需要编的程序的难度 。编计算器时甚至连代码都不是很明白，利用MFC做计算器的封面就更难了，不过经过这次课我还是学到了很多东西，比如更了解
Visual C++，对Visual C++的运行机制、类、消息处理等的理解都有了明显的提高，并且对MFC的操作也了解了一点皮毛。
