C# - Round numbers to 0 decimals

Question

Hi

I need to round numbers to 0 decimals (for a pagging system).

I've already tried something like this:

Math.Round(double1, 0, MidpointRounding.AwayFromZero);

If the double1 be 7,2 or 7,6 i need it to round for 8 but i'm not getting that.

Can someone help me, please?

Thanks

Answer 1

Use Math.Ceiling to always round up to the next integer:

double roundUp = Math.Ceiling(double1); 

Answer 2

If you don't want to use Math.Ceiling, for some reason - you could do:

 public int Ceil(double x) {
  return (int) x + ((int) x < x ? 1 : 0);
 }
