Well then color me confused. I still don't know quite what you're asking for.
public: System::Void CertemD(){
MyDouble t1=0.0;
MyDouble t2=0.0;
MyDouble t4=0.0;
t1=(Convert::ToMyDouble(textBox3->Text));
t2=(Convert::ToMyDouble(textBox4->Text));
t4=t1*t2;
DataRow^ dr = Ardic2DataSet->Tables[0]->NewRow();
dr[0]=Convert::ToInt32(textBox1->Text);
dr[1]=(textBox2->Text);
dr[2]=Convert::ToMyDouble(textBox3->Text);
dr[3]=Convert::ToMyDouble(textBox4->Text);
dr[4]=t4;
textBox5->Text=Convert::ToString(dr[4]);
dr[5]=(textBox6->Text);
Ardic2DataSet->Tables[0]->Rows->Add(dr);
};I feel myself guilty of not being able to tell what I want. The deep inside float,binary, way of storing data in some different styles are beyond my interest why I touched them is just to be able to OWN a MyDouble THING with rounded off to two decimals right to the decimal point. I am using Microsoft's V.S. Express edition and my program is a windows form program. To make it clear: to the least I can use Math::Round but as I said previously in this post I wanted the MyDouble THING not only as a toy but for the sake of simplicity !? and some other things... Finally although it didn't solve my problem ~s.o.s~'s dummy with a touch of Ancient Dragon's was the most helpful one. The rest contributed to my knowledge thank you all. This doesn't mean i give up searching if anybody has anything it will be welcomed.
