How do I round a float upwards to the nearest int in C#?

If you want to round to the nearest int:

int rounded = (int)Math.Round(precise, 0);

You can also use:

int rounded = Convert.ToInt32(precise);

Which will use Math.Round(x, 0); to round and cast for you. It looks neater but is slightly less clear IMO.

If you want to round up:

int roundedUp = (int)Math.Ceiling(precise);
