void CMyCalculatorDlg::Calculate(void)
{
switch (m_operator.GetAt(0))
{
case '+':
m_first+=m_second; break;
case '-':
m_first-=m_second; break;
case '*':
m_first*=m_second; break;
case '/':
if(fabs(m_second)<=0.000001)
{ m_display="整数不能为零！";
UpdateData(false);
return;
}
m_first/=m_second; break;
}
m_second=0.0;
m_coff=1.0;
UpdateDisplay(m_first); //更新编辑框显示内容
}
