simple

Question

Hi i would like to know how to get rid of of the decimals if i have a number eg: 2.56 changed to: 2.

i've tried the Math.Round() but it rounds to the nearest 10 I just want the decimals away. I tried changing the double to an int variable. I probably dont know how cause I got stuck trying.

I know this is a simple problem to solve I dont know y im taking stuck with it. Any ideas?

thanks

In that case you could use either of the following which both round towards zero (so -2.56 rounds to -2): double d = 2.56; d = (double)Decimal.Truncate((decimal)d); // OR (better): d = (double)(long)d; or you could use this which rounds to the lower integer (so -2.56 rounds to -3): double d = 2.56; d = Math.Floor(d);

Hi thanks I don't have that function though. Im using VS2003

If you're using .NET 2.0 or greater I'd use the Math.Truncate() method for this: http://msdn2.microsoft.com/en-us/library/c2eabd70(vs.80).aspx
