Decimal precision

Kev D

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.) 2,4567000 to 2,45 ? 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.
