MFC做小型计算器

部分代码

void CTest02Dlg::OnBUTTONcheng() 
{
	// TODO: Add your control notification handler code here
	
		
	UpdateData(1);
	
//	m_editnumber3=atof(m_editnumber1)+atof(m_editnumber2);

	m_editnumber3.Format("%.2f",atof(m_editnumber1)*atof(m_editnumber2));



	UpdateData(0);
}

void CTest02Dlg::OnBUTTONchu() 
{
	// TODO: Add your control notification handler code here
	
		
	UpdateData(1);
	
//	m_editnumber3=atof(m_editnumber1)+atof(m_editnumber2);

	m_editnumber3.Format("%.2f",atof(m_editnumber1)/atof(m_editnumber2));



	UpdateData(0);
}

void CTest02Dlg::OnBUTTONquyu() 
{
	// TODO: Add your control notification handler code here
	
		
	UpdateData(1);
	
//	m_editnumber3=atof(m_editnumber1)+atof(m_editnumber2);

	m_editnumber3.Format("%d",(int)atof(m_editnumber1)%(int)atof(m_editnumber2));



	UpdateData(0);

}
