I think the procedure should read:

procedure TsCustomNumEdit.SetText(const AValue: string);
var
  Val:  String;
begin
  if not (csReading in ComponentState) then begin
    Val := TextToValText(AValue);
    if Val <> '' then FValue := CheckValue(StrToFloat(Val))
                 else FValue := 0;
    DataChanged;
    SkinData.Invalidate;
  end;
end;

But again: this stems from a TsDBCalcEdit control that’s being filled from the database. Not by the user. Why do you want to do a CheckValue in that case? What possible correction can the user make if the Min/Max message pops up? He/she is not editing the field at that time, program logic may even prohibit editing of the field!

I think function TsCustomNumEdit.CheckValue should should start off like this:

begin
  Result := NewValue;
  if not Modified then Exit;   // Accept any value if field is not entered by user
  if FMaxValue <> FMinValue then
.
.
.

That would not cure the Conversion error above, but would once and for all get rid of unmanageable data errors.
