Auto rounding of double values

Someone has any idea how can I auto round double values to 2 decimal digits? I have an application which performs some sim开发者_开发问答ple calculations in many places and sometime I'm getting numbers with a lot of decimal numbers such as 21.248123. Is there any way to specify .NET to use only 2 decimal number in every place (through CultureInfo maybe?).

Thanks

You can do this at least when displaying the message to the user by using myDouble.ToString("0.00").

If you want to round the value itself use Math.Round(myDouble,2).

Note that even when rounding the double, you might get many decimals due to floating point aritmetics, so I would use the former ToString variant regardless when displaying the value to the user to make sure that it gets displayed with only two decimals.
