I'd like to apologize in advance for these questions. I know they're incredibly basic.

Using ASP.NET with C#, can somebody please tell me how to round a result either using a ASP.NET rounding method or a C# operation (or both)?

For example, what is the easiest and most appropriate way to convert a decimal value of 113.9764995 as 113.98 BEFORE assigning it to my variable?

Also, if 113.9764995 is saved in my variable, using ASP.NET, how can I DISPLAY it as 113.98 without actually changing the value in my variable?

Finally, I'd be very appreciative if anybody can refer me to either a C# or ASP.NET resource (or resources) of conversion functions to perform such tasks. I've searched high and low on a number of sites for the answer to these questions, but haven't had any luck.

Don't apologize, this is the Beginnings forum after all. :)

Take a look at the System.Math class at the MSDN Library .Net Framework Reference site for the details of all the math methods you can perform including System.Math.Round(). I think the specific one you want is here. You should be able to get all the documentation you need from there.

If I may offer a correction to your terminology. When doing something like rounding, you are not really doing a conversion. Converting implies a change of data type. You could certainly convert a manipulated number if you so choose but you don't need to.

To answer your last question, something like this should work:

lblMyResultLabel.Text = Math.Round(myDecimal, 2).ToString(); //Round to 2 places

Work smarter, not harder.

I dont recall what the exact syntax is for rounding but one thing to note is that .Net makes use of Bankers Rounding. There is an older thread on round and the effects of bankers rounding in the archives. I would suggest taking a look at that. If this form of rounding does not give you the results that you are looking for you may need to build your own rounding class.

Beautiful! Thanks to both of you. I actually came across many discussions of "Banker's Rounding" when performing searches to find the answer to this problem. Good to know.

Peter, thanks for your help ... especially drilling into the MSDN site for me. I know about this resource, but navigating it has been difficult. I hope to be able to find my way around in due time.
