Well, I hadn't imagined that there are several rounding standards. Here in Germany I only learned to round up each something.5 to the next integer at school. Now, I've seen the bank rounding which round up and down.
But what I want to do is not bank rounding but scientific rounding: always round up every .5 to the next greater integer. Does anybody know how to do that? System.Math.Round doesn't support any flags to set up the rounding standard :( Jochen -----Urspr�ngliche Nachricht----- Von: Tom Cabanski [mailto:[EMAIL PROTECTED] Gesendet: Montag, 9.

If you think about it, that is actually more accurate that always rounding as .5 is exactly in the middle and we should round up about half the time and down the other half of the time. This is one of the first platforms that behaves the way I would expect in this area. ------------------------------------- Tom Cabanski -----Original Message----- From: Rodolfo Campero [mailto:[EMAIL PROTECTED] Sent: Monday, February 09, 2004 12:29 PM To: [EMAIL PROTECTED] Cc: [EMAIL PROTECTED] Subject: RE: [Mono-list] Maths I get the same results with csc from MS .NET 1.0. >From: "Jochen Wezel" <[EMAIL PROTECTED]> >To: <[EMAIL PROTECTED]> >Subject: [Mono-list] Maths >Date: Mon, 9 Feb 2004 19:14:20 +0100 > >Hi! > >Has anybody seen that behaviour yet which is produced by MS .Net? > >When rounding doubles to integer, there is a rounding error: > Console.WriteLine(Convert.ToInt32(1.5)) 'is 2 - should be 2 > Console.WriteLine(Convert.ToInt32(2.5)) 'is 2 - should be 3 > >This may be important for those guys who are programming in that area... > >Jochen _________________________________________________________________ Add photos to your e-mail with MSN 8.
