}

a=itemp;

else if(m_str.GetAt(i)=='.')

rate=0.1;

a=sin(a*3.1415926/180); m_str.Format(\pass1=0;

UpdateData(FALSE);

13、sqrt功能的实现

void CLuxiaoyingDlg::OnSqrtButton18() {

// TODO: Add your control notification handler code here // if(addt!=0);//DENGYU(); double a,itemp=0,rate=10.0; int i;

UpdateData(TRUE);

for(i=0;i

if(isdigit(m_str.GetAt(i))) {

if(rate==10.0) { }

41 1

itemp=itemp*rate+(m_str.GetAt(i)-'0'); if(i==m_str.GetLength()-1)

a=itemp;

42

}

}

}

else { }

itemp=itemp+rate*(m_str.GetAt(i)-'0'); rate=rate/10;

if(i==m_str.GetLength()-1)

a=itemp;

else if(m_str.GetAt(i)=='.')

rate=0.1;

a=sqrt(a);

m_str.Format(\pass1=0;

UpdateData(FALSE);

//if(m_num!=0);

14、tan功能的实现

void CLuxiaoyingDlg::OnTanButton27() {

// TODO: Add your control notification handler code here double a,itemp=0,rate=10.0; int i;

UpdateData(TRUE);

for(i=0;i

if(isdigit(m_str.GetAt(i))) {

if(rate==10.0) {

42 1

43

}

}

}

}

itemp=itemp*rate+(m_str.GetAt(i)-'0'); if(i==m_str.GetLength()-1)

a=itemp;

else { }

itemp=itemp+rate*(m_str.GetAt(i)-'0'); rate=rate/10;

if(i==m_str.GetLength()-1)

a=itemp;

else if(m_str.GetAt(i)=='.')

rate=0.1;

a=tan(a*3.1415926/180); m_str.Format(\pass1=0;

UpdateData(FALSE);

15、菜单功能的实现

void CLuxiaoyingDlg::OnChengMenu() { }

void CLuxiaoyingDlg::OnChuMenu() {

43 1

// TODO: Add your command handler code here OnChengButton15() ;

44

}

// TODO: Add your command handler code here OnChuButton16() ;

void CLuxiaoyingDlg::OnCosMenu() { }

void CLuxiaoyingDlg::OnDaoshuMenu() { }

void CLuxiaoyingDlg::OnDengyuMenu() { }

void CLuxiaoyingDlg::OnJiaMenu() { }

void CLuxiaoyingDlg::OnJianMenu()

44 1

// TODO: Add your command handler code here OnCosButton23() ;

// TODO: Add your command handler code here OnDaoshuButton19();

// TODO: Add your command handler code here OnDengyuButton20();

// TODO: Add your command handler code here OnJiaButton13();
