Thanks for your suggesions and answers i got the answer after lots of searching and trial and error , I got whatever i want, so i use the following solution.
Once again for than you guys for your help.
public static Double myRound(Double Value, int places = 1000)
{
Double myvalue = (Double)Value;
if (places == 1000)
{
if (myvalue - (int)myvalue == 0.5)
{
myvalue = myvalue + 0.1;
return (Double)Math.Round(myvalue);
}
return (Double)Math.Round(myvalue);
places = myvalue.ToString().Substring(myvalue.ToString().IndexOf(".") + 1).Length - 1;
} if ((myvalue * Math.Pow(10, places)) - (int)(myvalue * Math.Pow(10, places)) > 0.49)
{
myvalue = (myvalue * Math.Pow(10, places + 1)) + 1;
myvalue = (myvalue / Math.Pow(10, places + 1));
}
return (Double)Math.Round(myvalue, places);
}
