I cannot see a problem.
Please provide FULL and EXACT information, property settings, event handler code, setup code, steps ...
I have MyEdit1..n and SumEdit. I enter values into MyEdit. I am updating the SumEdit value as you type.
An example of SumEdit.FloatValue is 100. I write 5 to MyEdtix. In MyEdtix.OnChange I have SumEdit.FloatValue: = MyEdit.FloatValue. The resulting value in SumEdit = 110.00 and not 105.00
Sorry, I was waiting for an e-mail :)
Edit:SumEdit.FloatValue: = SumEdit.FloatValue + MyEdit.FloatValue
It's all me. The most important:
Precision = 2
EditType = etMoney
Thanks for reporting the issue was resolved.
We don't understand a bit. The Precission property must be greater than 0. Otherwise, an "error" will not occur. The "Formating" event, and consequently the OnChange event, does not occur.
I retested this with 3 default TAdvEdit controls on the form and the code:
procedure TForm2.AdvEdit1Change(Sender: TObject);
begin
advedit3.FloatValue := advedit1.FloatValue + advedit2.FloatValue;
end;
procedure TForm2.AdvEdit2Change(Sender: TObject);
begin
advedit3.FloatValue := advedit1.FloatValue + advedit2.FloatValue;
end;
procedure TForm2.FormCreate(Sender: TObject);
begin
advedit1.EditType := etMoney;
advedit1.Precision := 2;
advedit2.EditType := etMoney;
advedit2.Precision := 2;
advedit3.EditType := etMoney;
advedit3.Precision := 2;
end;
I cannot see any moment that the calculation is wrong here.
I sent a primitive form to try it on.
