Rounding to the next whole number

I'm trying to find a function that will round up to the next whole number; I read that the round() function does exctally that, however, When using the immediate box with the following code

This returns the result 1 (the nearest whole number) rather than 2 (which is the next whole number)

Can anyone help me out with this?

Thanks, this works to make 5/4 = 2 but it also make 4/4 = 2 (when I need it to equal 1)

This looks like it will work for what I want. Thanks everyone for all the help!
