Decimal precision

Question

Hello I have decimal vars which I retrieve from my database. They have a precision of 7 digits. I want to use these to calculate various things and save them in an other database with only 2 digit precision. So how can I set my (eg.) 24567000 to 245 ? Thanks in advance !

Here you go: double n num; string snum; Console.Write(Enter number to round: ); snum = Console.ReadLine(); num = Convert.ToDouble(snum); n = num * Math.Pow(10 2); n = Math.Floor(n + .5); num = n / Math.Pow(10 2); Console.WriteLine(The rounded number is {0} num);

See Truncate() method in help. Round() method works very strange - it isn't mathematical round.
