Round up - C# / C Sharp

How can I round up a float number?

For example:

If I have a number 3.6 I want to obtain 4 and

If I have a number 3.1 also to obtain 4

Thanks a lot.

Oops. That won't work if n has no fractional part.

Ruslan,
Have you tried System.Math.Ceiling? Which returns the smallest whole number
greater than or equal to the specified number.

Note for negative numbers it will return numbers closer to zero.

Ceiling(-3.6) will return -3.

The function System.Match.Floor will return the smallest whole number less
than or equal to the specified number.

Hope this helps
Jay
